Sleep is strategy. Nobody makes their best moves at 3 a.m. on their fourth energy drink.

Judgment is the first thing to go when you are tired, and it goes quietly, so you feel fine while making worse and worse calls. Late at night everything seems either urgent or hilarious, and neither reading survives daylight. Rest is not the reward for finishing the work. It is part of the equipment you do the work with.

Set a time when the phone goes on the charger and the decisions stop. If something feels desperately important at two in the morning, write it down and look again after breakfast. Most of the time the note will read like someone else wrote it.
