When I say potential, I'm talking about your own personal/mental abilities.
Not about external factors that you couldn't control(such as poverty, abuse, irresponsible relatives, borderline criminal behavior from institutions), that made your abilities 10x less useful in that context and your efforts 10x less efficient.
Like honestly when I describe some aspects of my life in details, people think I'm making shit up.
I'm not talking about some guys who think they're smart and don't do anything about it.
I'm talking about growing up in the worst hood in your country, not having a single young neighbor who didn't spend some time in jail, getting physically assaulted almost daily for years, dealing with racists teachers when you get into a school outside your hood, having to deal with your father's eviction notice at 14 because he's too freaking stupid to take care of it, landlords near your college rejecting you because you're not white, having to live in abject conditions just so you can go to college, actually starting college 4 months late after everyone because you couldn't find a place to live. That's not even half of it.
I don't personally know a single person(with similar mental abilities)from the middle class, or even the lower middle class, who's doing worse than me.
