Hahahahahaha! Brilliant.
I'm a bit of a hypocrite here, because I have effectively "monetised" (if you'll forgive my use of an obscenity) my hobbies. I write fiction and sell it. I make money from my film reviews and other articles on cinema. It's what I do for a living as a full-time writer (yes, I do some other freelance bits and pieces, but most of my money comes from what were once my hobbies). :)
