For years, I assumed that if travel was becoming less exciting, the answer was obvious:
Go somewhere new.
A different country. A different city. A different coastline. Somewhere I hadn’t seen before.
For a long time, that worked.
There was genuine excitement in discovering Southeast Asia: Thailand, Cambodia, Vietnam, the Philippines. The same was true closer to home. Over the years I travelled around Britain through Cornwall, Devon, Dartmoor, the Peak District, the Lake District, the Welsh coast, Northumberland, Shropshire and many places in between.
I wanted to see them.
The curiosity was real.
But eventually something changed.
I became less interested in travelling somewhere new while becoming more interested in repeatedly exploring places I already knew.
That seemed contradictory.
Surely somewhere 300 miles away that I had never visited should be more interesting than somewhere five miles from home that I had walked twenty times?
Yet increasingly it wasn’t.
A road trip could feel like effort for surprisingly little reward. Meanwhile, a familiar local landscape could still pull me back because I had discovered some forgotten history, an obscure ruin, another footpath, a photographic possibility or simply wanted to see the same place in a different season.
The geography was becoming more familiar.
But the experience was becoming richer.
Eventually I realised that I had been treating two very different forms of discovery as though they were the same.
Breadth and depth.
That distinction may explain far more than why my enthusiasm for conventional travel has declined.
It may also explain why my everyday life at home works so much better than the everyday baseline I have repeatedly created abroad.
I call the missing variable The Depth Deficit.
Travel Gives Us Breadth Almost Automatically
Travel is exceptionally good at creating breadth.
We visit another city.
Cross another border.
See another landscape.
Encounter another culture.
Photograph another coastline.
Hear another language.
Eat something unfamiliar.
Early in a lifetime of travel, that breadth can be immensely rewarding because the world still contains so much that is genuinely new to us.
I don’t want to retrospectively dismiss this as superficial.
It wasn’t.
When I first travelled around Southeast Asia, the contrast with ordinary life in England was enormous. Bangkok felt extraordinary because Bangkok was genuinely unfamiliar. Pattaya felt extraordinary because I had never experienced anything remotely like it. Cambodia and Vietnam opened up yet more territory.
The unfamiliarity itself had value.
The same happened with road trips around Britain. There were places I had wanted to see for years. Travelling to Dartmoor or the Lake District wasn’t a desperate attempt to escape boredom. I genuinely wanted to experience those landscapes.
Breadth mattered because there was still a great deal of breadth I actually wanted.
But breadth contains a hidden weakness.
Its value depends heavily on novelty.
And novelty depreciates.
A New Destination Can Produce a Familiar Experience
After enough travel, the locations remain different but the process begins to feel remarkably similar.
Research a destination.
Book somewhere to stay.
Drive or fly there.
Find the recognised attractions.
Visit the famous viewpoints.
Photograph or film them.
Eat somewhere.
Move on.
Repeat.
The map keeps changing.
The behavioural pattern doesn’t.
I previously explored that repeating pattern as the Travel Treadmill.
That is an important distinction.
A destination can be geographically unfamiliar while being experientially familiar.
Cornwall is not Northumberland.
Vietnam is not Thailand.
But after enough travel, visiting another unfamiliar destination can still feel like another iteration of a process you already know extremely well.
This doesn’t mean the place itself is boring.
It means that novel geography no longer guarantees novel experience.
Eventually, you can find yourself accumulating places without accumulating very much meaning.
And that produces a subtle but important change in motivation.
There is a difference between:
having somewhere you genuinely want to go
and
wanting to have somewhere to go.
The first begins with curiosity.
The second can become repetition disguised as exploration.
Breadth Depreciates — Depth Can Compound
The breakthrough came from noticing that the opposite process was happening at home.
If familiarity causes boredom, why could I repeatedly explore the same relatively small area without becoming bored with it?
The answer was that I was no longer relying on novelty.
I was developing depth.
Depth works differently from breadth.
Breadth expands the number of places you have encountered.
Depth expands what a place means to you.
You begin learning the roads, footpaths and landscapes.
You discover history that isn’t immediately visible.
You notice ruins you previously passed without understanding.
You learn how an area changes through the seasons.
You revisit somewhere under different light.
You investigate why a building is there.
Photography causes you to observe details you once ignored.
Research sends you somewhere you would never have found through a generic visitor guide.
One discovery produces another question.
That question produces another journey.
The geographical territory may barely increase, while your relationship with it becomes progressively richer.
So familiarity can create two completely different outcomes.
Passive familiarity can produce boredom.
But active familiarity can produce depth.
That distinction explains something that conventional travel thinking often misses.
A place can be geographically familiar while becoming experientially richer.
That is almost the mirror image of the travel problem.
Away, the geography changes but the experience increasingly repeats.
At home, the geography repeats but the experience can continue changing.
That is the central paradox behind The Depth Deficit.
Depth Is More Than Knowledge
Depth is not simply knowing facts about somewhere.
It is accumulated engagement with a territory.
Knowledge is part of it, but depth also includes repeated experience, familiarity, competence, curiosity, context and connection.
You begin understanding how places relate to one another.
You stop seeing isolated attractions and start seeing systems.
A ruin connects to a historical period.
A footpath connects to an old settlement.
A landscape makes sense because you understand the geology.
A village changes because you know what used to be there.
A location becomes photographically interesting because you have seen it in January, May and August rather than once on a sunny afternoon.
Depth changes perception.
It allows you to see more without necessarily travelling farther.
This is why a long-term local observer can uncover something that a highly experienced traveller passing through will probably never notice.
The traveller may have considerably more breadth.
The local observer has resolution.
Roots and Depth Are Not the Same Thing
This distinction forced me to reconsider another idea I had been using to explain why extended travel eventually pulled me home:
roots.
I have strong roots at home.
Those roots matter.
Roots involve belonging, security, personal history, familiarity, attachment and the feeling that somewhere is fundamentally your territory.
But I had been allowing roots to explain too much.
Because roots and depth overlap without being identical.
Someone can have strong roots somewhere while possessing surprisingly little depth of engagement with the place itself.
They may have family, property, work and friendships there. They may have lived in the same town for thirty years.
But if their everyday life consists largely of work, television, shopping and the same limited routines, they might know relatively little about the landscape around them.
They have roots.
They may not have much depth.
Conversely, someone could spend several months intensely exploring a foreign location, learning its history, improving their language, understanding how the surrounding area works and repeatedly investigating it.
They may never consider that place home.
They may have no intention of settling there permanently.
But they can still develop considerable depth.
That distinction matters because:
Roots are difficult to transplant.
Depth may be portable.
Perhaps My Roots Weren’t the Only Thing Pulling Me Home
For a long time, I interpreted the recurring pull back home during extended travel quite simply.
My roots were in England.
Therefore, eventually I wanted to return to England.
That may still be true.
But it now looks incomplete.
What if I wasn’t merely returning to my roots?
What if I was returning to my deepest life?
At home I had accumulated layers.
Photography.
Landscape.
History.
Familiar territory.
Projects.
Knowledge.
Places I still wanted to investigate.
Skills I wanted to improve.
One interest connected naturally into another.
Meanwhile, once the initial excitement of being abroad weakened, my everyday routine could become remarkably thin.
Walk in the morning.
Find breakfast.
Have a coffee.
Edit something filmed the previous night.
Walk some more.
Wait for the evening.
This was not equivalent to what I actually did at home.
I had been comparing a deep home baseline with a shallow away baseline and attributing the difference mostly to roots.
The concept of depth explains the comparison much better.
The Missing Away Baseline
I have previously thought about travel in terms of baseline and peak.
The baseline is ordinary daily life.
The peak is the intense contrast sitting above it.
Thailand, particularly in earlier years, could provide an extraordinary peak.
Nightlife.
Sexual opportunity.
Hedonism.
Novelty.
Excitement.
A radically different environment.
That contrast had enormous power.
But a peak can only remain a peak if it is not constant.
Repeated exposure produces adaptation.
Eventually Tuesday morning arrives.
Then Wednesday.
Then Thursday.
And underneath the extraordinary moments you need an everyday existence that works.
This is where my away life repeatedly struggled.
The peak could be powerful.
The baseline underneath it was often too weak.
Once novelty adapted and the peak became less reliable, there was not enough remaining to answer the most basic question:
Why am I still here?
The peak was being asked to carry the entire trip.
That is an impossible burden over long periods.
Home then became increasingly attractive because the baseline waiting there had far more depth.
This is where The Depth Deficit becomes more than an observation about sightseeing.
Depth may be one of the missing ingredients required to build a sustainable away baseline.
Why Slow Travel Alone Does Not Solve the Problem
This also explains why I have always felt slightly unconvinced by vague advice about slow travel.
I had already begun considering a slow-travel experiment through Southeast Asia, but something was still missing from the idea.
Stay longer.
Stop rushing.
Spend a month somewhere instead of a week.
Live locally.
That all sounds plausible.
But there is an obvious objection:
What exactly are you doing with the extra time?
Renting an apartment for three months doesn’t automatically create a meaningful life.
You can stay somewhere slowly while remaining psychologically shallow.
Have coffee.
Walk around.
Scroll your phone.
Edit yesterday’s footage.
Visit another café.
Wait for something to happen.
Three months of that is not depth.
It is simply a longer weak baseline.
Slow travel can therefore become slow breadth.
Instead of consuming a destination in four days, you consume it in four weeks before moving to the next one.
The speed changes.
The underlying relationship with place may not.
So slow travel is not the solution.
It is better understood as infrastructure.
Slow travel provides something depth absolutely requires:
time.
But time alone is insufficient.
A better formula is:
Time + engagement = the possibility of depth.
Slow travel gives you the time.
You still have to do something with it.
Depth Also Requires Commitment
Time and engagement may still not be enough.
There is another important difference between home and travel:
Home has permanence. Travel has optionality.
When boredom appears at home, moving somewhere else usually isn’t the answer. You remain within the same territory and eventually have to look harder at what is already around you.
Travel makes escape much easier.
The novelty fades, a grey period arrives, and the obvious response is:
Move on.
Another town. Another island. Another country.
Novelty returns, but so does breadth. The traveller never remains in one place long enough to discover what lies beyond the obvious layer.
That suggests boredom may have been sending me the wrong message.
When you live somewhere, boredom often makes you look deeper. When you’re travelling, boredom often makes you look elsewhere.
If depth is going to be portable, an away base may therefore require a degree of simulated permanence.
Not pretending it is home. Not forcing myself to stay somewhere I genuinely dislike. But committing to a place for long enough that the first period of boredom does not automatically trigger another move.
For that period, the question changes from:
Where should I go next?
to:
What haven’t I understood about where I already am?
Perhaps that grey period is not evidence that the experiment has failed.
It may be the point where novelty ends and depth finally has the opportunity to begin.
Depth requires time — but it also requires enough commitment to survive the end of novelty.
Transplanting the Pattern
That creates a much more useful question for future travel.
Instead of asking:
Could I spend six months in Thailand?
or:
Would Cambodia work as a long-term base?
I can ask:
Can I transplant the pattern that makes my life at home interesting?
That pattern is surprisingly simple.
Research something.
Go and investigate it.
Photograph it.
Film it.
Learn its history.
Discover something unexpected.
Follow the next lead.
Return somewhere under different conditions.
Understand more of the surrounding landscape.
Develop local competence.
Learn some of the language.
Build projects.
Allow one discovery to generate another.
The location changes.
The behavioural structure remains.
That is fundamentally different from travelling through somewhere.
It is an attempt to convert an unfamiliar destination into a territory with increasing personal depth.
Depth Creates Purpose
This matters because depth produces something else that has often disappeared during longer trips:
purpose.
When you are genuinely investigating somewhere, tomorrow already contains possibilities.
There is a location you want to visit.
Something you want to understand.
A historical thread you want to follow.
A photograph you want to attempt.
A video you want to make.
A question you have not answered.
That changes the psychological structure of the day.
Instead of asking:
How do I fill today?
you begin asking:
Which thing do I pursue today?
That difference is enormous.
Purpose doesn’t necessarily require some grand life mission.
Often it is simply the existence of a meaningful next step.
Depth continually generates those next steps because increased understanding creates more questions rather than fewer.
The Day Stops Becoming Something You Wait Through
This has an important implication for hedonistic travel.
If the away baseline is weak, daytime can gradually become little more than the space between nights.
You walk.
Eat.
Edit.
Wait.
Then nightlife begins.
The evening carries the emotional weight of the whole trip.
But imagine a different structure.
Monday is spent investigating a historical site.
Tuesday you return somewhere to film it properly.
Wednesday you research something discovered there.
Thursday takes you into the countryside.
Friday you edit or write.
Then Saturday night you go out.
Now the night is no longer responsible for making the entire week worthwhile.
The week was already worthwhile.
The peak becomes contrast rather than purpose.
That is a fundamentally healthier relationship between baseline and peak.
It also suggests that the original problem may have been framed incorrectly.
Perhaps the challenge was never:
How do I make the peak last?
Perhaps it was:
How do I create an Away Good Life underneath it?
The Away Good Life
At home, the Good Life does not necessarily provide extreme excitement.
Its value comes from a baseline that works.
Meaning.
Interest.
Projects.
Familiarity.
Depth.
Mastery.
Purpose.
Structure.
Travel historically gave me something almost opposite.
Extraordinary peaks sitting above an ordinary life abroad that eventually became too empty.
That created a recurring oscillation.
I had previously described this as living between two worlds.
Home: rich baseline, weak peak.
Away: rich peak, weak baseline.
Eventually I returned.
The Depth Deficit suggests a new possibility.
If depth can be developed abroad, perhaps the away baseline doesn’t have to remain weak.
That creates the possibility of an Away Good Life.
Not a replica of home.
Not new permanent roots.
Not emigration.
Simply an everyday life abroad that remains sufficiently rich that I am not continually waiting for the next peak or thinking about returning home.
Then the structure becomes:
Away Good Life + occasional hedonic peak.
That is the combination I have never properly tested.
Breadth Still Has a Purpose
None of this means breadth has become useless.
Breadth may simply need a different role.
Instead of being the end goal, it can become reconnaissance.
Travel around.
Experience places.
But rather than automatically asking where to go next, start asking a different question:
Does this place make me want to know more?
If not, move on.
If yes, stop.
Breadth can help identify locations capable of generating curiosity.
Depth begins when somewhere stops being just another point on the itinerary and starts producing questions.
So perhaps future travel does not need to choose between breadth and depth.
The relationship can be sequential.
Breadth discovers candidates.
Depth develops the relationship.
Curiosity Is the Gatekeeper
There is an important limitation.
Time cannot manufacture curiosity.
I am naturally interested in the history and landscape of my own country.
Would I become equally interested in the history of Cambodia?
Vietnam?
Thailand?
I don’t know.
That is one of the central uncertainties in the experiment.
But there is also a reason not to assume the answer is no.
Abstract interest in “Cambodian history” is not the same as discovering a particular ruin, wondering what happened there, visiting it, learning its story and then finding that the answer leads to another location.
Curiosity is often generated by contact.
A subject becomes interesting because something concrete makes you want to understand it.
So foreign depth may prove weaker than home depth.
Or the unfamiliarity of the history may make the investigative process even richer.
There is no reason to decide the answer theoretically.
It needs to be tested.
Mobility Is Infrastructure for Depth
There is another practical variable that initially seemed minor but may be fundamental:
mobility.
At home, independent transport dramatically expands the territory available for exploration.
If I discover something interesting twenty miles away, I can simply go there.
That freedom is easy to take for granted.
Take away the car and a large proportion of spontaneous exploration becomes considerably harder.
You become dependent upon railway stations, bus routes, organised transport, taxis or tourist infrastructure.
That matters because tourist infrastructure is generally excellent at taking visitors to the places everyone already knows about.
Depth often begins when curiosity leads somewhere less obvious.
So mobility is not merely a convenience.
Mobility can determine how much depth is practically accessible.
The solution will vary.
Rental car.
Motorcycle.
Scooter.
Bicycle.
Public transport.
Ride-hailing.
Occasional hired driver.
But if the hypothesis is going to receive a fair test, mobility needs to be considered part of the experimental design rather than treated as an afterthought.
Environment, Language and Culture
Mobility isn’t the only obstacle.
A foreign environment creates additional friction.
Heat.
Humidity.
Monsoon seasons.
Different road systems.
Language.
Cultural misunderstanding.
Limited access to historical material in English.
These can all make depth harder to develop.
But they may also become part of the process.
Learning enough of the language to communicate.
Understanding local customs.
Learning when to explore around the climate.
Becoming competent with local transport.
Gradually understanding what you’re looking at.
These activities themselves create depth.
An unfamiliar culture is initially difficult partly because it lacks context.
Context accumulates.
And context changes experience.
Purpose Changes the Meaning of Friction
This also changes how I think about travel friction.
Heat is irritating when you are wandering around because you have nothing particularly important to do.
Transport is irritating when you’re travelling somewhere merely to fill another day.
But suppose you have spent two days researching an obscure historical location and genuinely want to find it.
The road has not improved.
The temperature hasn’t fallen.
But the friction now exists between you and something you actually care about reaching.
Purpose doesn’t eliminate discomfort.
Purpose changes the meaning of discomfort.
That distinction may be important in understanding why some forms of difficult travel remain satisfying while seemingly easier trips become tiresome.
The question isn’t merely how much friction exists.
It is whether the destination on the other side of that friction matters to you.
Could Depth Help Explain Why Moving Abroad Works for Some People?
There is a broader implication to The Depth Deficit, but this needs to remain explicitly a hypothesis.
I have often heard people who successfully moved abroad recommend immersion.
Learn the language.
Get away from tourist areas.
Buy transport.
Explore.
Understand the culture.
Live locally.
I’ve sometimes dismissed those arguments because I genuinely like my home country.
Why should I manufacture a replacement for something I already value?
But perhaps some of those people have been describing depth-building behaviours without naming them as such.
Maybe some had relatively little depth of engagement with the place they left.
Maybe others had plenty of depth at home but successfully learned how to recreate the pattern abroad.
Maybe over years they accumulated enough depth that the new location eventually developed roots as well.
There is no evidence that this single variable explains expatriation generally.
It obviously doesn’t.
People move for relationships, economics, climate, work, dissatisfaction, family, lifestyle and countless other reasons.
But depth suggests a useful question that cuts across those explanations:
What exactly are you leaving behind, and what are you capable of building where you’re going?
Someone leaving a shallow home life may have relatively little experiential depth to miss.
Someone leaving a very deep home life may feel that loss much more strongly.
And someone capable of rapidly developing depth abroad may eventually construct an everyday life strong enough to compete with what they left behind.
That may help explain why advice from successful expatriates has sometimes failed to resonate with me.
They may not simply be saying:
You should prefer another country.
They may be saying:
You need to stop treating it like somewhere you’re visiting.
That is a very different proposition.
Roots May Follow Depth — But Depth Does Not Require Roots
There may also be a sequence here.
Time → engagement → depth → attachment → perhaps eventually roots.
But the important point is that the process does not need to reach the final stage.
For extended travel to work, I don’t necessarily need Cambodia or Thailand to become home.
I don’t need to stop valuing England.
I don’t need to imagine permanent emigration.
I only need sufficient depth to make the temporary baseline worthwhile.
That separation is liberating because it removes an impossible condition.
Previously, I could reason:
My Good Life works because I have roots. I cannot quickly create roots abroad. Therefore the away baseline will always remain inferior.
The Depth Deficit changes that.
Perhaps roots contribute substantially to my home life.
But perhaps depth is one of the portable components.
And if depth contributes significantly to the quality of the baseline, then there is something I can actually experiment with.
A Better Experiment
The first test should therefore not be:
Can I live abroad for six months?
That asks too much and measures too many variables at once.
A better experiment is:
Can I successfully transplant my depth-building behaviour into one foreign location?
That means establishing a base.
Limiting the territory.
Giving myself enough time.
Solving mobility.
Actively investigating.
Following curiosity.
Learning.
Photographing.
Filming.
Revisiting.
Building projects.
Gradually increasing competence.
And observing what happens after the initial novelty fades.
The important moment isn’t the first week.
Of course the first week is interesting.
The important moment is later.
After adaptation.
After the obvious attractions.
After the initial excitement.
What happens then?
If I reach the second or third month and still wake up thinking:
There is something here I genuinely want to investigate today
then something important has changed.
The away baseline has developed substance.
What Would Disprove the Theory?
A useful hypothesis also needs the possibility of failure.
Perhaps I deliberately attempt this and discover that depth abroad never approaches the value of depth at home.
Perhaps cultural interest does not transfer.
Perhaps climate and mobility reduce exploration too much.
Perhaps the absence of roots matters far more than I currently think.
Perhaps I enjoy developing depth for six weeks but then lose interest.
Perhaps the pattern works in one location and fails completely in another.
Any of those outcomes would be useful.
The point of the experiment isn’t to prove that I should live abroad.
The point is to identify whether The Depth Deficit really was one of the major reasons my previous away baselines failed.
If deliberately developing depth changes the experience, the theory gains support.
If it doesn’t, then another missing variable remains.
Depth Does Not Replace the Primary Pull
There is an important point I don’t want to lose in all this discussion of depth.
Depth is not necessarily what would make me travel halfway around the world in the first place.
If all I wanted was history, landscape, photography and meaningful projects, I already have those things at home.
The Primary Pull of places such as Thailand has historically been something different: the possibility of a hedonic peak that my ordinary life at home does not provide.
That distinction remains.
The problem was never simply that the peak had disappeared. The problem was everything surrounding it.
A Saturday night might still provide enormous contrast, but Saturday night cannot sustain a three-month trip. There are mornings, afternoons and entire weekdays between those peaks, and eventually that ordinary time becomes most of the experience.
That is where the Depth Deficit matters.
The peak may provide the reason to go. Depth may provide the reason to stay.
If I can build an Away Good Life through exploration, history, photography, landscape, learning and genuine engagement with a place, then the daytime no longer becomes something I endure while waiting for the night.
It becomes worthwhile in its own right.
And that could actually restore something valuable to the peak as well: contrast.
After several days genuinely absorbed in the place around me, a Saturday night out becomes a transition into something completely different rather than another attempt to make an otherwise empty week worthwhile.
That is the combination I am really interested in testing.
Not depth instead of hedonism.
Not hedonism instead of the Good Life.
A compelling everyday baseline with access to an occasional peak.
Perhaps that is what a sustainable Away Good Life would actually require.
Maybe I Wasn’t Bored With Travel
This brings the argument back to where it started.
Why can somewhere familiar become more interesting while somewhere unfamiliar becomes less compelling?
Because familiarity and novelty may not be the variables that matter most anymore.
Early travel was driven by breadth.
Breadth delivered huge rewards because unfamiliarity itself was valuable.
But eventually breadth began depreciating.
Another country still added geography.
It no longer necessarily added much discovery.
Meanwhile, at home, something different was happening.
I was going deeper.
A familiar landscape kept generating more value because accumulated knowledge changed what I could see within it.
That suggests a different approach to whatever travel comes next.
Perhaps I don’t need to travel farther.
Perhaps I need to stop somewhere long enough to stop merely travelling through it.
To investigate rather than consume.
To accumulate knowledge rather than destinations.
To develop a relationship with a place without demanding that it become home.
Perhaps what repeatedly pulled me back wasn’t simply that my roots were at home.
My deepest life was there.
And if I want an extended life away to work, perhaps I don’t need to transplant my roots.
I need to transplant the pattern that created that depth.
The question is no longer:
Where else can I go?
It is:
Where could I go deep enough that staying becomes interesting?
Maybe I haven’t become bored with travel.
Maybe I’ve become bored with breadth without depth.
