You have to also love making money. I love making money. By definition, it is impossible for me to become unhappy if I have to make money doing what I love. /obvious.

I had a girlfriend like this: she was an excellent photographer, had a degree in fine arts with a photography specialty, but didn't want to make money doing it -- she didn't want it to become her job. This discrepancy made her miserable, not only because she generally didn't get to take pictures, and didn't get to make the money she could be making, but also because she wasn't using her degree.

I went to school for CS, not because I love it (though I do at times) but because the market forecast was good, and I wanted to retire early. What I like about programming is the freedom to innovate, to solve problems. I get to solve problems, solve puzzles with my job. That's great. When I get done working, I'll write a book -- that'll be even better.

I think it's enough to work doing something you like, to support what you love.
