You are not the next Chris Cox.
That is not pessimism. It is precision. You can study this path, but you cannot inherit its conditions, replay its sequence, or schedule its luck.

Two forces, no new scores
Perseverance and luck both matter.
Documented perseveranceNot documented in the reviewed biographical summaries.Silence in a biography is not evidence that perseverance was absent.
Structural luckCox entered Facebook at ~23 as an early engineer via the Stanford AI/Symbolic Systems pipeline during the social-network structural wave, contributing to News Feed and rising to CPO.This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Sequence matters
