I always see what’s. . . wrong. Would you want that? When I see a car or a rocket or spacecraft, I only see what’s wrong. I never see what’s right. It’s not a recipe for happiness.
I tried to eat better too, but when you're on tour you literally just eat some hideous pork pie on the motorway on the way to a show. It's a really unhealthy lifestyle: you're up late, drinking loads of coffee to stay awake, drinking loads of alcohol because you're socialising with people.
