By the time I was 9, I was frequently asked to play exhibitions at grand openings, fund-raisers for charities, and other special events.

In Toronto, Serena Williams was not fit at all, not striking the ball well at all, and went three sets with someone (ranked) 92 in the world.

From one match to the next, I kept on winning.

Winning that first game was so important; my mother always said that the first game of the second set was the chance to keep it going if you were ahead or change things if you were behind.

We've gotta give Richard Williams a lot of credit - to give us two number one champions is a phenomenal feat.

I won the Wimbledon mixed doubles title in 1980.

To meet my goals, I couldn't let up when I was playing tennis.
