It doesn't happen all the time, but when I'm playing well it's as if my eyes change. I can feel it. I just feel like Dr. Jekyll and Mr. Hyde-a transformation happens, I'm a totally different human being. I don't hear anybody, I don't see anybody, nothing bothers me, nothing is going to interfere with what I'm about to do.
Don't become too narrow. Live fully. Meet all kinds of people. You'll learn something from everyone. Follow what you feel in your heart.
