What is deep work scheduling?

Deep work scheduling is a concept in personal epistemology: Assigning specific blocks of time to specific types of work ensures important work gets done.

Example: A software engineer spends Monday through Friday 'working on the product,' but every week ends with the same realization: the critical database migration never started. She tried willpower. She tried prioritization frameworks. Nothing changed — until she blocked Tuesday and Thursday mornings, 9 to 11:30, exclusively for deep technical work. Within two weeks the migration was complete. The time was always there. What was missing was the assignment.

This concept is part of Phase 42 (Time Systems) in the How to Think curriculum, which builds the epistemic infrastructure for time systems.
