"I made a lot of mistakes, and I still do. But, I try not to worry about it, because I never will be the perfectionist, and I never tried to be, I guess. Just so they didn't come out all, mussed up. I don't think anyone knows his own work. We always make mistakes about what we like and what we don't like. One can never tell, I've done so many things that I've no idea about how to evaluate them."
