"Once I get on something, once I have something that I'm working on, then I become very obsessive. In a good way. I mean,... is there a positive way to say obsessive? It's a good thing and if you're out there and you're working on something right now and you're crazed and you're up in the middle of the night, or you can't stop thinking about it, or you have to keep reading other things about the subject that you're working on or whatever. That's good and I think that's necessary creatively."
