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.
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.
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.
Where humanity is going to find itself in, say, 20, 30, 40, or 50 years would be very difficult to predict, I think. There are moments, of course, when you think that it's going from bad to worse, but there are other moments when you think that human efforts are really flowering into something really fantastic.
I've done a couple of conferences where you sit and sign autographs for people, and then you have photographs taken with them and a lot of them all dressed up in alien suits or 'Doctor Who' whatevers. I was terrified of doing it because I thought they'd all be loonies, but they are absolutely, totally charming as anything. It's great fun.
