No career is fulfilling to anyone with more than half a brain unless they are ok making someone else wealthy, doing what they are told, beholden to others (be it bosses or customers/clients)etc (aka being a cuck).
Anytime away from doing what I really want to do is a chore, a job and that's why you/we get paid for it...I have far better things to do with my time than spend it "working". I only do it because I'm a normie and it's required to be part of modern civilization (unless you are independently wealthy of course).
Even if I started doing something I enjoy as a job...I'd no longer enjoy doing it because it was now a job...been there done that.
