keefbaker's hit the nail on the head, I think. If I play the things I want to play, with people I enjoy playing with, I'm happy not to make much - I used to play for a living , but have a decently paid day job these days. But if I'm expected to play music I can't stand/have played to death and put up with drunks/nonsense, it ceases to be fun and I expect to be paid for my trouble.
