Julia Child didn't learn gourmet cooking until her late 30s.

I think part of the trouble is that that the definition of "mastery" is so fluid. In chess, is "grandmaster" really the bar you want to set? Why not just "master" or even "expert?"

In another area, some percentage of medical doctors receive their degrees after age 40. Is that achievement + licensure sufficient to call it "mastery?"

Colonel Sanders has to exemplify the late bloomer. From odd job to odd job, he was broke at age 65 before he franchised out what is now KFC. 10k+ hours of frying chicken without anything to show for it. His decision to sell on his recipe to restaurant owners changed all that.

Lesson: Master a skill that you can franchise and protect.
