I would go all day long if I could, but alas, I haven't reached the point where fractalling pays the bills. Still, I work at home on the computer, so I tend to "reward" myself every half hour or so by adding another layer to whatever I'm working on at the time. Often I can't stop rewarding myself until 4 or 5 AM. (And no, that's not a euphemism for anything unsavory.) I can tweak all day long on one picture and still tell myself I'm "working." :)
