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

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.

If you can react the same way to winning and losing, that's a big accomplishment. That quality is important because it stays with you the rest of your life, and there's going to be a life after tennis that's a lot longer than your tennis life.

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.

Whatever your goal in life, be proud of every day that you are able to work in that direction.

You can't give up! If you give up, you're like everybody else.

Losing hurts me. I was determined to be the best.
