Your Brain Only Commits the Diffs

Why five years at the same job feels like a long weekend

A colleague once told me he had fifteen years of experience. His manager, in a rare moment of honesty, replied: "You have one year of experience, fifteen times."

Brutal. Also, physiologically accurate.

Here is the mechanism. Your brain does not store duration. It stores change. It works like a version control system with aggressive deduplication: if today is byte-identical to yesterday, no commit gets written. Same alarm, same commute, same standup where six people say "nothing from my end", same lunch, same evening scroll, same bed. Nothing new to encode, so nothing gets encoded. And when you later ask your memory "how long was that?", it does not count days. It counts commits.

Empty log, short history. That is time compression - and it is why a week of travel feels longer in hindsight than the four months of office routine that funded it.

Researchers have a name for the small-scale version: the oddball effect. Drop something unexpected into a stream of repetitive stimuli and the brain rates the surprise as having lasted measurably longer than the identical repeats around it. Attention spikes, uncertainty spikes, encoding spikes. The stretch is on the order of tens of milliseconds in lab conditions - tiny, but it proves the machinery exists. Scale it up to weeks and you get the reason your thirties evaporated.

There is also the arithmetic nobody enjoys: a summer at eight years old is a huge slice of everything you have ever lived. A summer at forty-five is a rounding error. You cannot fix that ratio. You can fix the commit rate.

The professional version is worse

Here is the part that does not make it into the wellness posts.

Time compression is not just a feeling problem. It is a career problem, and it has a receipt.

Routine is compression, and compression is exactly what makes you replaceable. If your working year fits into a diff so small the brain skips it, your job description fits in a script. The people who feel like life is racing past them are very often the same people whose work has become so patterned that it could be documented once and automated twice. The boredom and the risk come from the same root cause: no novelty, no new information, no new value.

Meanwhile the power horse 🐎 next to you who keeps picking up the ugly unfamiliar escalation, the migration nobody wants, the customer with the impossible architecture - that person is miserable in the moment and rich in memory afterwards. Novelty is uncomfortable by definition. Comfort is the absence of new information. You get to pick one.

The cruel bit: comfort feels like stability and looks like risk management. It is the opposite. A routine that is perfectly stable is also perfectly describable, and anything perfectly describable is on somebody's efficiency roadmap.

How to raise your commit rate

Not a self-care checklist. A deliberate campaign against sameness.

👉 Change the small physical variables first. Different route, different supermarket, different chair, different order of the morning. Cheap, immediate, and it drags your brain out of autopilot without a single meeting invite.

👉 Once a quarter, take on one piece of work you are visibly unqualified for. Discomfort is the encoding signal. Also the fastest promotion mechanism I have ever seen, and nobody believes me until they try it.

👉 Single-task on purpose. Attention is the write buffer. Half-present days do not get saved - they get dropped, along with the conversation you were technically part of.

👉 Write three lines before sleep. Not a gratitude ritual, a changelog. What was different today? If you cannot answer for five days running, that is not a mood. That is a diagnostic result.

👉 Book the trip before you feel ready. Anticipation plus unfamiliar geography is the highest-yield memory investment per euro that exists. Nobody on their deathbed reminisces about a well-maintained backlog.

👉 Refuse the flat year. A year with nothing in it is not a neutral year - it is a year your memory will quietly garbage-collect.

Time does not accelerate. Your logging does. The clock never changed its speed. Your life just stopped producing anything worth writing down.

👇 What was different about your last week - anything at all? If you had to think about it for more than ten seconds, you already have your answer.
