I'm of the opinion that a lot of people if not most arguably don't really make a choice about who they are. They don't live with intentionality, they don't consider their agency, they just run on autopilot with the baseline personhood they were built with.
I think you are spot-on with this, and that it very much includes many "successful" people who others automatically assume they should try to emulate. It's especially bad here in the US.
