The main thing is to care. Care very hard, even if it is only a game you are playing.

You have got to want to be the best before you can even begin to reach for that goal, and you have got to be prepared to sacrifice a lot to get there.

I got to see the best players in the world every year the week after the U.S. Nationals, which is now known as the US Open, in Los Angeles. That made a huge difference in my life.

I always respect right off the bat because we are human, but then over time you learn who the person truly is, just like they learn about you. Hope it works out really well, and you hope that builds a stronger connection over time. You can't be friends with everybody.

It's very important to take tennis to the people. For young people, they get to see the best in the world.

Bobby Riggs was one of my heroes. I admired him. That's one of the reasons I beat him - because I respected him.

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.
