The big push for me is the Olympics this year. If I'm healthy, I'm not worried about my ranking. I think I can hit the ball. It's just about my body cooperating. It's about being able to play matches in a row. Right now, I'm not sure how much I can do with that, but we'll see.

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.

My first job is big sister and I take that very seriously.

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.

Everybody's got their problems. The important thing is not to complain about it.

I LOVE RIHANNA. I LOVE THAT SHE IS HERSELF WITH NO APOLOGIES. HER SENSE OF STYLE AND SELF IS UNIQUE. I LOVE HOW SHE TRANSFORMS HERSELF WITH EACH ALBUM, EACH CAMPAIGN. ALWAYS EVOLVING. A TRUE ICON.

The thing about tennis is if you stay off for two weeks, or just for three days, you can lose your rhythm quickly. So it's just a question of constant diligence and vigilance.
