> I could put in all the hours of practice and guided training into boxing as Mike Tyson and I wouldn’t get nearly the same results.

I think this fails to recognise the talents that Mike Tyson has leveraged: the soft skills and gumption to identify the best trainers, the best team, the best opportunities, and to seize those, being motivated to gain fame and plaudits. Plus consistent, world-class training and experience on top - working outside of the 30 hours of class.

These skills are very transferable to other fields. Look, for example, at the George Foreman Grill.

Could you have done the same? Yes, I think it's possible. But, viewing it as only practice and guided training seems like a fundamental error.
