It's all about genetics, being born to the right parents/family, first world country, and demographics.
Your non genetic impulses are almost entirely determined by your parents and upbringing, so it's not like anyone has any real agency in life.
Everything was determined from the moment you were conceived as to whether you'll be a failure or not. Learning and improvement has nothing to do with motivation, an ability to successfully learn and improve is all genetic despite what overly optimistic teachers would tell you. Otherwise chimpanzees and dolphins would be starting fires!
Even if everything is determined, there is still the journey itself. I mean... ok, maybe I couldn't avoid any of the mistakes I made, but it was still sort of cool to have developed a beyond massive theory when I was in late elementary school, about other humans being puppets of a demon who forced a strict caste and used them as his eyes and ears, and emotions being physical forms translated in the mental realm thus enabling you to metamorphose. Certainly it was all a massive mistake, for which I paid dearly in later years, but it was impressive nonetheless.

Now, hopefully, if I ever have to relive the same life, I will at least pick different paths in the thousand forks of the road.
