Silence is golden when you can't think of a good answer.

Age is whatever you think it is. You are as old as you think you are.

When I won the Golden Gloves in 1960, that made me realize I had a chance. And when I won at the Olympics, that sealed it: I was the champ.

I had a good time boxing. I enjoyed it - and I may come back.

I don't have to be what you want me to be.
