Why Thousands Lie

Something happened when that number dropped from nine-sixty to three-sixty: It got worse (of course) – but it also got a lot more real. Four thousand weeks never managed to do that for me – even though the same math, done in weeks, leaves me somewhere around thirteen hundred. Over a thousand feels like plenty, a few hundred does not.

Which is what this chapter is about: The smaller number is the one you can feel. It’s 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.

For me the line sits at about a thousand. Anything above – 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 went viral. 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. The number of 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. 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.

Burkeman’s 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 – a grid I’ve stolen for the cover of this book. Urban gave it the visual; Burkeman gave it a book, and somewhere right now one of those dot-grids is pinned to a fridge, slowly fading in the sun.

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. But 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 on the far side of a thousand, everything past 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.

The change to make 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, bigger unit, smaller count – and suddenly the number stops being a feeling and starts being a quantity.

Because hundreds – hundreds you can hold.

A few hundred of something stays this side of the 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. 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 can’t avoid: Plans don’t work on feelings. A budget doesn’t work on “a lot of money,” nor does a diet 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 count is too big. The drawer eats the warning.

And it’s why nine hundred and sixty months (minus what you’ve already spent) do.
