Ever since that day when I was 11 years old, and I wasn't allowed in a photo because I wasn't wearing a tennis skirt, I knew that I wanted to change the sport.

Tennis taught me so many lessons in life. One of the things it taught me is that every ball that comes to me, I have to make a decision. I have to accept responsibility for the consequences every time I hit a ball.

Natural talent only determines the limits of your athletic potential. It's dedication and a willingness to discipline your life that makes you great.

I feel that tennis is an art form that is capable of moving the players and the audience - at least a knowledgeable audience-in almost sensual ways. When I'm performing at my absolute best, I think that some of the euphoria I feel must be transmitted to the audience.

I like putting money back into what made my life, and tennis has been great to me.

Be bold. If you're going to make an error, make a doozy, and don't be afraid to hit the ball.
