## The framework
- Every experience is judged against your North Star: the thing you are actually trying to move forward.
- Contribution: Does this advance my North Star, build relevant skills, create valuable connections, or provide essential learning?
- Distraction: Does this consume time and energy without advancing my purpose, create busy work, or pull me away from core objectives?
- Mixed: Which parts contribute and which distract, and how do I separate them?
- Four pillars: External checking (How to evaluate others and be the good vibe yourself: the "vibe check"); External experience (Learning from the world through systematic expansion of your discomfort zone); Direct environment (Gauging and optimising your surroundings for growth); Self-reflection (Internal tracking and truthful identity assessment).
- Progress is measured by the quality of your self-reflection and the calibre of the people you attract into your life.
- Behavioural science lenses: BJ Fogg's Behavior Model, Yu-kai Chou's Octalysis framework, Gary Keller's The ONE Thing, Eric Ries's The Lean Startup, Robert Cialdini's Influence.
