Rest is maintenance, not a reward for reaching collapse.

Rest is part of how the machine works, not a prize for having damaged it. Waiting until collapse means the rest becomes repair rather than upkeep, takes far longer, and arrives after the decisions made while depleted have already had their effects. The cheapest rest is the kind taken before it is deserved.

Schedule recovery in advance the way you would schedule anything necessary. An evening, a day, a proper night. Do it when you do not feel you need it yet.
