For almost 40 years now, my hobby, my passion has supported my life (and a few other lives beyond that). I've done lots of other things for other people, went to college to please my dad, got a phd because my mom though I should. But always there was the art, the show. It's taken very good care of me. But you can't do it forever. And so my other hobbies are writing, collecting stories, and taking pictures - pictures that other people can't take, never take. Some of them are on my flicker site, but only a few, out of the thousands and thousands I have. And when I can no longer do the art, no longer do the show, I'm going to tell the stories - with pictures - the way my phd taught me to tell them, and I hope that those hobbies and those passions will support me once the show is gone and people better than me, or at least younger than me, are doing it. The show must go on, and it will.
The point is, you have to follow your bliss. Do what you love, and it will never seem like work, never seem like a chore, and you'll never wake up thinking "damn I have to go to work today" but instead you'll wake up on your off days thinking "->-bleeped-<-, I don't have work today."
Most people sell themselves too short, for too much money. Neither brings happiness.
