What is quantified self dashboard?

Quantified self dashboard is a concept in personal epistemology: A personal dashboard transforms scattered signals into a coherent picture of your current state — making drift visible before it becomes crisis.

Example: You track sleep, exercise, deep work hours, relationship quality, and financial runway in a single weekly view. One week you notice sleep dropping while deep work hours climb. Without the dashboard, you'd have called that 'being productive.' With it, you see the unsustainable trade-off in time to correct it — before burnout forces the correction for you.

This concept is part of Phase 10 (Externalization Mastery) in the How to Think curriculum, which builds the epistemic infrastructure for externalization mastery.
