It's really impossible for athletes to grow up. On the one hand, you're still a child, still playing a game. But on the other hand, you're a superhuman hero that everyone dreams of being. No wonder we have such a hard time understanding who we are.

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

I like entrepreneurial people; I like people who take risks.

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.

I have a lot to say, and if I'm not No. 1, I can't say it.

When I was playing, we didn't have to compete against everybody in the world. Now it's a truly global sport, so the competition's much greater, just like it is for our children in every other area, whether it be in science or technology or whatever you talk about.

Don't worry about what people say.
