Mike,

I think thats a great question "if I knew I'd NEVER make a penny doing this thing I love, would I still do it?". I would suspect most people including myself would answer that yes. That's essentialy what most of us do anyway maybe without admitting it. Still it gives us the chance to dream. Not sure if this or the lottery has longer odds But I doubt many people would buy lottery tickets if there no jackpot.
Besides you can't pull out a losing lottery ticket and stick it in the CD player and sing to yourself in the car.
