One of my thoughts is that it's not easy for people to discover what they're truly good at. The reason is that if you're truly good at something, if you have a real talent for it, then it's easy for you to do it well from the start, so you rarely judge it or realize how good you are. Just as no one thinks they're good at their heartbeat and breathing. Because you have the talent to be good at them from the beginning,…
Talent, drive, inherent traits interacting with learnable traits, learning curves, etc. What you are good at. What you are good at getting better at.
"Blank slate" is a better ethic. It's sort of the basis for modern public/political moral perspectives. But also for personal ethos... the "growth mindset* is a much better ethos and mentality.
But Otoh... we are who we are. We have the body we have. The genes we have. The childhood development we have. The education and experience we have. The personality we have. Etc.
We don't really have the have the culture of weighing these, and "knowing ourselves" via a mattwr-of-fact, calculating examination.
