Tell a fish success is measured by climbing a tree, and he will spend his whole life thinking he’s a failure.
What skills, attitudes, personality traits have you seen mismatched to a certain job that later made the individual an awesome worker in another job?
I wasn’t outside of getting upset at my mom growing up, and when that would happen, she used to joke “if I was your dad, I’d be a success.”
In all seriousness, one good example I know of is game testers make bad game designers. Back when Nintendo was making Mario Kart 8, they discovered some of the people actually overseeing production actually had bad vertigo (purportedly including Iwata and/or Miyamoto), so they’d invite them in to see the games being tested so they could see if it triggered their vertigo which they would attempt to fix, then repeat cycle. Now had those people with vertigo been making the games, we probably would’ve gotten simple Diddy Kong style race tracks.
