The normal standard of living on earth is; be born, go to school, graduate, secure a job, marry, have children, train them, and die. No one ever ask, what do you want to do, are you happy with what you're doing, is this what you want from life?
Sometimes you wonder why some certain people engage in professions they don't love, other times you wonder why you do what you do when you're not happy.
It all comes down to the controlled environment set by the myopic minded predecessors we have. Most times, it isn't their fault, because that's how they met the world.
To find success, look for what makes you happy, even if it is just a hobby, then monetize it. You can only be successfully happy when you do what you love.
