Treat future you like a teammate. Don’t leave them a mess to clean up at the buzzer.

Every choice you make today hands something to the version of you who wakes up tomorrow, and that person has no say in it. Most exhaustion is not caused by the amount of work but by the arrangement, by things left where they will have to be dealt with at the worst possible moment.

Spend five minutes each night setting up the start of the next morning. Clothes out, bag packed, first task decided. It costs almost nothing now and removes a surprising amount of friction later.
