I'd love to claim that what I have done in my life is of my doing, but it's not of my doing at all. I've blown around in the wind like a mad thing, influenced by this and that - like a piece of paper: like the boy in that scene in 'American Beauty' watching a piece of paper blowing hither and thither.
You can see areas where maybe you got a bit lazy, perhaps, or you see when you were really on form. I think an actor is very like a sportsman in that respect. You have periods where you're in terrific form. Everything you touch seems to work and come right. And other times, when you're working really hard, it's okay, but it isn't scintillating.
The most difficult thing about painting is the self-discipline. When I finish a job, I give myself a few days, but then I have to discipline myself quite fiercely if I want to do some painting that's worthwhile. Otherwise, you're just doodling. It's much easier when you're just told what you have to do.
