I work for perfection, for perfection's sake. I don't care what the external reasons are. And it's much more like a ballerina on opening night. You've done what you've got to do. When you go out, the purpose is to turn a perfect turn. You are not thinking about the future of the company, you are not thinking about your future, you're not thinking about the critics, it is you and the perfect turn.
