What is self-healing systems?

Example: You build a weekly review habit where you check three key metrics every Sunday — energy level, output quality, and alignment with quarterly goals. For the first month you have to force yourself through it. By month three, you notice something has shifted: the review is no longer just observation. It has become corrective. When energy drops two weeks in a row, you automatically reduce commitments the following week. When output quality flags, you trace it to sleep disruption and adjust your evening routine. When alignment drifts, you prune projects that looked urgent but were not important. You are no longer catching errors after they compound. The system catches them at the point of emergence and routes corrective action before you consciously intervene. The review is not something you do to your system. It is something your system does to itself.

This concept is part of Error Correction in the How to Think curriculum.
