Ten Decisions, One Sitting

There's a particular kind of ambition that ruins a Saturday: the plan to "finally sort out the whole house." It starts well — genuine energy, real intent — and by item forty, something has quietly changed. The decisions aren't getting easier with practice, the way you'd expect. They're getting harder, slower, more exhausting, until "keep" starts winning by default, not because it's the right answer, but because deciding anything else takes energy that ran out two hours ago.

That's not a willpower problem. It's decision fatigue — a widely observed pattern where the quality of decisions can decline the more of them you make in a row, regardless of how important each individual one is. The most famous evidence for it comes from a study of parole-board judges, whose rulings grew measurably harsher over the course of a session and reset after a food break — a finding that's been debated and re-examined since, as good research usually is, but the underlying shape of it matches something most people recognise from their own long afternoons: deciding gets harder to do well, the longer you've been at it.

Ten is not a small number. It's the right one.

Ten decisions in one sitting sounds modest, almost too modest to bother with. That's the point. It's enough to make genuine progress — a real dent, not a token gesture — while stopping well before the point where fatigue starts quietly making your decisions for you instead of you making them. Not too much, not too little. Just enough, on purpose, rather than however much momentum happens to carry you before it runs out.

Stopping on purpose isn't giving up

The instinct, mid-session, is often to push through — you're on a roll, why stop at ten. Worth resisting that instinct more than it looks like you should. The tenth decision made while fresh is a better, truer decision than the fortieth made while depleted. Stopping at ten isn't settling for less. It's protecting the quality of the nine you already made, and the ten you'll make just as well next time, instead of spending all of today's clarity in one exhausting afternoon and calling it finished.

Small, repeatable, and honest about its own limits — that's the whole method, really, not just this last piece of it.
