I think there's more stressful periods than others when you're launching new things or going into a new business, or there are many things that can stress you out. Having to let people go, that's stressful. Never fun. But for the most part, I try to manage a schedule that's achievable and try not to make a schedule that's not. And a lot of times, sometimes it becomes a little unmanageable, but in spurts. So I think being able to make an achievable schedule, one that I know I can accomplish.

Life is challenging but I'm always up for a challenge.

I think that Billie (Jean King) and Zina (Garrison), they have a whole lot of experience. Even if I don't quite agree with something or have a different way of doing it this week, whatever they said, I did it right away and I found out that it was correct. I think that's helped a lot...I'm having fun. I had a lot of fun out there. Sometimes I was ready to smile -- but I knew I'd lose focus -- because I was doing things that I'd done in practice and we talked about. I was ready to laugh and give someone a high-five, but it wasn't time for that.

To be a well-rounded person and know what's going on in the world around you, to have a perspective outside of your sport, is important for every athlete. I'm blessed that our parents gave us that.

I guess tennis is my main art, but fashion is definitely very close.

When you lose, you're more motivated. When you win, you fail to see your mistakes and probably no one can tell you anything.

Whoever is across the net, I want to win. Whoever that person is, that's the day I want to win.
