When to schedule the work that needs a closed door
A thesis, a deadline draft, an exam, a proposal that has to be finished in one sitting — this scenario looks for the days your attention holds and your energy is steady. It is the least traditional of the seven: no almanac has an entry for "deep work," so the traditional layer is deliberately weighted down here and your own state curve does most of the work.

Sustained focus — pick a day with fewer distractions and a smoother cognitive load
