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

I knew my destiny was to be in the winner's circle. There were times along the way where I didn't make it there. But I felt my destiny was definitely to win big titles, win lots of titles.

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.

My parents always told us, you know, you have to get your education. You're not supposed to become a statistic.

We've been training and playing full-time since we were 18 and 19. So after tennis, we'll be excited to see what it's like to have more free time.

I have been recently diagnosed with Sjogren's Syndrome, an autoimmune disease which is an ongoing medical condition that affects my energy level and causes fatigue and joint pain.

Some people say I have attitude - maybe I do...but I think you have to.
