Principlev1
Design daily schedules around your finite deep work capacity
Design daily schedules around your finite deep work capacity rather than attempting to maximize total work hours or distribute effort uniformly across the day.
Why This Is a Principle
Synthesizes depletion (Directed Attention as Depletable Resource), ultradian/circadian rhythms (Ultradian and Circadian Cognitive Rhythms), and chronotype variation (Human cognitive capacity varies predictably across the day). The principle prescribes accepting the 3-4 hour deep work limit and structuring the day accordingly rather than fighting biology. This is the integrated implication of Phase 4's energy management frame. Actionable and general.
