I think Ive done the best I could have done. But I keep wanting to play better, go further. There are so many sounds I still want to make, so many things I havent yet done. When I was younger I thought maybe Id reached that peak. But Im 86 now, and if I make it through to next month, Ill be 87. And now I know it can never be perfect, it can never be exactly what it should be, so you got to keep going further, getting better.
