Rest is a move, not a pause from the game. Tired players make predictable mistakes.

Fatigue does not announce itself as fatigue. It arrives as impatience, as taking the first option, as saying yes because arguing costs too much, and every one of those is easy to predict from outside. Rested people have more moves available to them. Treating recovery as time away from the work is what makes the work worse.

Put one real rest block in the week and defend it the way you would defend a deadline. Sleep counts more than anything else here. Watch your judgment on the days after, because that is what pays for the time.
