The thing is, it's not good anyway for eight-year-olds to be out there playing tennis tournaments so soon in their lives. But when I did get to play in a tournament, when I was nine, I was overjoyed.

In my mind, I'm always the best. If I walk out on the court (and) I think the next person is better, I've already lost.

Losses have propelled me to even bigger places, so I understand the importance of losing. You can never get complacent because a loss is always around the corner. It's in any game that you're in - a business game or whatever - you can't get complacent.

Well, when I walk behind short people I feel like I'm going to fall over because I start taking these little steps, and I can't take little steps.

I think business is the same as tennis. You have to have the love, that helps, or else it's just too much pressure to be able to keep up with.

I don't have time to be negative.

People ask me where I get my fighting qualities from, and I have to say Serena.
