When I committed to playing a little tennis in some exhibitions, it was the best thing for me. It got me in shape. It got me out of the house. It got me doing something I love to do.

I guess I get my strength from my legs, which are also important in tennis.

I'm not worried about the weekend, I'm worried about Saturday.

I made it look so easy on court all those years. No one realized how hard I had to work. No one realized how much I had to put into it. They underestimated my intensity.
