What is track energy levels daily?

Track energy levels daily is a concept in personal epistemology: Track what activities give you energy and what activities drain you over a typical week.

Example: A software engineer logs her energy across four dimensions for seven days. She discovers that pair programming sessions, which she had always classified as "draining meetings," consistently raise her mental and emotional energy by two to three points. Meanwhile, solo code reviews after 2 PM — work she considered easy and low-stress — drop her mental energy from a seven to a four within forty-five minutes. Her subjective narrative about what gives and takes energy is almost perfectly inverted from what the data shows. The audit does not change her activities. It changes her understanding of them, which changes everything about how she schedules her day.

This concept is part of Phase 36 (Energy Management) in the How to Think curriculum, which builds the epistemic infrastructure for energy management.
