Never make a big call on low battery. Charge first, then choose.

Decisions made while depleted tilt reliably toward the pessimistic and the dramatic, because a tired mind sees fewer options and weighs the bad ones heavier. What feels like clarity at the end of a hard day is usually narrowness instead. The same facts produce a different answer after food and sleep.

Make a rule that big choices wait until you have eaten and rested, and treat the rule as settled. Write down what you are inclined to do, then read the note once you are recovered. If it still holds, go ahead, and if it does not, you have saved yourself something.
