The evening review

Before the morning forecast can work, you need the thing that feeds it: an honest look back at the day you just had. Not a guilt spiral. A review. The mechanic walks the bay before lockup and sees what got left half-done. The teacher, driving home, replays the lesson that lost the room. You can do the same with a whole day, and the Stoics built a practice around it.

Epictetus, the freed slave who taught philosophy in a bare room, handed his students an old verse to use each night, before sleep: "Also allow not sleep to draw nigh to your languorous eyelids, / Ere you have reckoned up each several deed of the daytime: / 'Where went I wrong? Did what? And what to be done was left undone?'" (Discourses 3.10, Oldfather). Three plain questions. Where did I miss? What did I actually do? What did I leave undone that I'd owned?

This is the heart of the week, and the engine of the whole habit. You can't aim tomorrow if you never looked at today. The look isn't punishment; you censure the base acts and you let yourself be glad about the good ones. A few honest minutes, and the day stops slipping through your hands unexamined.
