Where it was dropped
+1Tailwind
Older brother sparked passion for math. No evidence of wealthy or academic parents. Montreal, Canadian family. Brother's mentorship was the key family advantage.
The shape of the track

University of Montreal for BSc and MSc, Cornell PhD under John Hopcroft (Turing Award winner). Met Charles Bennett at a conference in 1979, launching quantum cryptography collaboration. Strong advisor and serendipitous collaboration.
Two forces, no new scores
Silence in a biography is not evidence that perseverance was absent.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.

The useful conclusion
Use this record for information, never for a verdict about your pace or worth.
