There are two aspects to making movies: One is the feeling of wanting to push myself into stuff that I don't know how to do. Then there's the other impulse to try and earn a living. I want to be careful about not confusing those too much - not that those things can't have a healthy overlap. Plenty of people start out making work that isn't terribly commercial, and then make work that's more commercial but still good. You just want to watch out for that thing where you tell yourself that you're doing your best work when you're not.
