>>6056956Success in life arises from genetic factors (gender, appearance, intelligence, neurodevelopmental status [freedom from mental disorder], etc.) in conjunction with environmental factors (birthplace, family support, wealth, access to opportunities).
No one likes to admit it, and survivorship bias distorts perception of the numbers, but it's very easy to fall through the cracks in society; ie. very few people ever escape the social class, let alone circumstances of their birth, and even something mild like being an introvert reduces your potential for success.
I suspect Marine had all the genetic markers for greatness but struggled with environmental ones.
