That’s a rare category, since typically people who are naturally good at something challenging spend a lot of time doing it. The equivalent white collar job would be a savant who quickly masters new fields without significant effort, but again, said savants typically spend a lot of time on their field of expertise anyway.

I suppose artists/musicians who have natural mastery of the canvas/instrument and thus don’t need to practice rote exercises much also fall into this category.

BTW, I disagree that a bouncer falls into that category—they need to constantly physically train in the gym to maintain their physique.
