I have a great family, great kids. I have practically everything, you know? Sometimes I have to pinch myself. It's really true: Life starts at 50.
I'm amazed that years after I stopped playing tennis, people still recognize me in restaurants and ask for my autograph.
The ball is round, the game is long.
You have to find it. No one else can find it for you.
When I retired from tennis I wanted to do other things with my life.
I wanted to win, even in practice.
