Hell, it doesn't even matter if you're good at what you do! I mean, look at Ed Wood or, Mandra help me, Uwe Boll. Regardless of talent, these people managed to throw all their wasteful passion into their work, and I'd like to believe they're happy doing what they do.
It's another conundrum. If you like doing it, why aren't you doing it? Ugh...More on this later down the road.
Peace ouch, guys.
