What is burnout prevention boundaries?

Burnout prevention boundaries is a concept in personal epistemology: Professional boundaries protect your work quality, your career development, and your well-being from the unlimited demands of organizational life.

Example: A senior engineer gets pulled into every architectural review, every hiring loop, every cross-team initiative because she's competent and agreeable. Her own project deadlines slip. Her deep work disappears. She starts working weekends to catch up, then evenings, then early mornings. She isn't failing at her job — her job is consuming her because she never defined what it could and could not demand. The day she blocks four hours of uninterruptible focus time and declines two standing meetings that don't require her, her output quality jumps visibly within a week.

This concept is part of Phase 33 (Boundary Setting) in the How to Think curriculum, which builds the epistemic infrastructure for boundary setting.
