If you do something you love, chances are you can make a really good living off of it so the money point is moot. This is because if you love what you're doing, you'll "work" harder at it. The more time you put into something, the closer you get to the 10,000 hour "expert" mark (see Outliers by Malcolm Gladwell). I can't think of any starving "experts" (unless they're starving because they blew their money, then I can think of a lot).
Now you might want to try a field that you don't particularly like if you can make a lot of money for a few years without a lot of schooling. Having a little nest egg to live off of will allow you to devote yourself full-time to whatever it is you love so that you get those 10,000 hours faster.
These fields include web development (salaries as high as $85k after exiting a 2 month training course, check out places like apprentice.io) and anything in the financial services industry (brokers, traders, etc).
