Luck sounds ethereal. But it can be distilled to a formula: (motion × knowledge) ^ environment.

Knowledge is your cerebral retention. Motion is how often you interpolate with situations where you can deploy your knowledge. Environment is the quality of the situations in which you deploy that knowledge.

In practice, motion should be given 1.5x the weight of knowledge. High knowledge + no motion = limited utility; packed cerebellum with nowhere to use it. High motion + no knowledge = marginal utility; plenty of opportunities, but limited ability to take advantage.

But environment carries the day. Low-density environment: limited opportunities and/or low-value opportunities. High-density environment: frequent high-value opportunities.

Being lucky isn't a birthright, it is a compounding skill.
