If you can react the same way to winning and losing, that's a big accomplishment.

Of all my achievements in tennis, I'm probably as proud of my record on clay courts as any of my Wimbledon, U.S. Open or French singles titles.

The difference is almost all mental. The top players just hate to lose. I think that's the difference. A champion hates to lose even more than she loves to win.

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

Don’t let a first-set victory lead into a second-set slump

If you're a champion, you have to have it in your heart. You can have the greatest coaches in the world, all the opportunities to play, and the greatest equipment, but if you don't have it inside, you're not going to make it. On the other hand, if you don't have any of those luxuries but you have heart and courage and the guts to go out there and grind it out, then you'll make it.

I've had a lot of fear in my life, from fear of flying to fear of making a speech in front of a lot of people.
