I'm an American. You can't go on where you were born. If you do then John McEnroe would be a German.

Just go out there and do what you've got to do.

The tennis ball doesn't know how old I am. The ball doesn't know if I'm a man or a woman or if I come from a communist country or not. Sport has always broken down these barriers.

The difference between involvement and commitment is like ham and eggs. The chicken is involved; the pig is committed.

Whoever said, 'It's not whether you win or lose that counts,' probably lost.

Changes made to please others are unrealistic, but more important, they're unfair to you.
