Why Thousands Lie

Something happened when that number dropped from nine hundred and sixty to three hundred and sixty. It got worse – and it got realer. Four thousand weeks never managed that – even if you do the same kind of math and find that I, as a fifty-something, have about one thousand five hundred weeks left. Over a thousand is plenty. A few hundred is not.

That’s the whole subject of this chapter: the smaller number is the one you can feel. Not because it’s more true – they’re both true, it’s the same life measured two ways – but because of where your brain files each one. And it files by size.

The line sits at about a thousand. Anything north of it – weeks, dollars, miles, take your pick – is too big to picture, and the brain has a specific place it keeps things too big to picture. Mine has a drawer. Anything past the line gets opened, shoved in there, and the drawer gets shut.

Look at what else is in there. Likes on a LinkedIn post that did better than expected. Steps on the fitness tracker at the end of a long day. The unread count on a friend’s inbox, the four-digit badge that should – and you’ll back me up here – be a criminal offense. Followers on whichever celebrity your kids cared about last summer. Views on a YouTube video that took off. Songs on Spotify, a hundred million of them, last I checked, though the drawer doesn’t really sort by size. The grains of sand on the beach, the stars on a clear night, the strangers who walked past you in a city today.

None of those are numbers, not the way three is a number. They’re feelings. And the feeling is always the same one: a lot.

Don’t blame the brain for this – it was never built for the job. Evolution shaped us to count a tribe, a herd, a bunch of apples. Robin Dunbar put the upper limit on stable human relationships at around 150 – Dunbar’s number, you’ve probably heard of it – and you can quibble with the figure, but the order of magnitude is the point. We are a hundreds species. Past that, we tag and move on.

Which is the trouble with the book I keep wanting to have worked on me.

Oliver Burkeman’s Four Thousand Weeks is good, and the thesis is exactly right: map a human life onto a wall calendar of weeks, and the number you get is shockingly small. About four thousand. He didn’t even invent the move – Tim Urban’s “Wait But Why” did the most haunting version of it back in 2014, a grid of dots, one per week, the rest of your life laid out like graph paper. Urban gave it the visual; Burkeman gave it a book; somewhere right now one of those dot-grids is pinned to a fridge, slowly going invisible the way everything on a fridge does.

It should land. And it does, intellectually. You read the line “four thousand weeks” and the rational part of your brain agrees with it the way it agrees with your tax return. Then it slides off.

That isn’t Burkeman’s fault. Or Urban’s. They were telling the truth. It’s the number. Four thousand is roughly a thousand, and a thousand is a lot, and you have already filed it.

A thing that is true but unfeelable does not change behavior. It’s a fact you nod at on the train.

So the move this whole thing rests on is small and stubborn. Take the same finite life and switch the unit until the count falls out of the drawer and onto the desk in front of you. Same life. Smaller container. Suddenly the number stops being a feeling and starts being a quantity.

Because hundreds – hundreds you can hold.

A few hundred of something stays the right side of a horizon. Close enough that you can still see it whole.

The minutes in a long movie. The episodes in a TV show you watched all the way through. The chapters in a Russian novel you keep meaning to finish. People at a wedding – full, but countable, names attached to most of the faces. The friends you’d actually cross an ocean to see. Numbers in the hundreds let you imagine each item. They let you place them. You can plan around a number that sits still long enough to be counted against.

And here is the part you cannot dodge.

Plans don’t work on feelings. A budget doesn’t work on “a lot of money.” A diet doesn’t work on “a lot of calories.” Your life, similarly, does not get planned against “a lot of weeks.” You can fear a feeling. You can pray about a feeling. You cannot allocate against one.

You can only allocate against a number.

Which is why four thousand weeks, true as it is, leaves you the same person it found. The unit is wrong. The drawer eats the warning.

And it’s why nine hundred and sixty months, halved by what you’ve already spent, doesn’t.
