Working definition
Personal Growth Engineering is treating yourself as the product: behaviours as features, ideal day as release criteria, and systems as the runtime that makes that day probable.
How it works
Most people collect knowledge and wait for motivation. An engineer ships: roadmap → features → runtime → measure.
You are the application. A new behaviour is a feature. Refining an old behaviour is a feature upgrade. The ideal day is not a mood board — it is the release criteria: what must be true for the day to count as shipped.
Then you build the system (nutrition · rest · people · tools · behaviours) that makes the features run without heroic willpower. Guarantee question: how do I know I am approaching this day? Contrast (missed wake window, skipped effort block) is the test suite.
Distinction from All Success Lies in Its Preparation: preparation is fuel check; Personal Growth Engineering is the product architecture — what you build into yourself and what the day must prove.
Signature
You are the application. Ship the feature. Run the day.

Your move this week
- List three behaviours (features) your current ideal day still lacks.
- Pick one · schedule it as a named block before Friday.
- Write one line: I know the day shipped when ___.

Roadmap behaviours as if-then features plus specific release criteria beat vague “grow more.”
