Even if you find a vocation that you generally enjoy, it doesn't mean that you will enjoy every part of it. I love to program, but there have been a number of jobs and tasks during my career that I definitely did not like.

I think this probably applies to every career. You have to navigate within your available options to balance things that pay well with the ones you enjoy doing.

I have a side project that I truly enjoy working on. It is big enough that I have spent years working on it in my spare time. I am still trying to find traction for it in the market. If it ends up making me a lot of money, then great; but if it never makes anything, I have still enjoyed building it.
