I wanted always to appear strong and in control . . . .Then the cookie began to crumble.

Competitive toughness is an acquired skill and not an inherited gift.

After being at the top, I don't think I could play senior tournaments, because you know how good you were. I don't know if I would enjoy that, being half of what I was.

Ninety percent of my game is mental. It's my concentration that has gotten me this far. I won't even call a friend on the day of a match. I'm scared of disrupting my concentration. I don't allow any competition with tennis.

Training the body to obey the mind as I have done differs from the more conventional method of getting the mind to obey the body.

I always looked ahead.

Find something that you're really interested in doing in your life. Pursue it, set goals, and commit yourself to excellence. Do the best you can.
