In tennis, at the end of the day you're a winner or a loser. You know exactly where you stand... I don't need that anymore. I don't need my happiness, my well-being, to be based on winning and losing.

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

Being famous before you've formed your personality, before you have that self-esteem, is dangerous.

Relationships are give-and-take, and when you're a tennis player, you're certainly not giving. You have to be self-absorbed. It has to be about you.

Every time, all the time, I'm a perfectionist. I feel I should never lose.

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.

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