If I didn't play tennis I don't know where I'd be.

The most fun part about working out is being done - getting through the workout, let's be honest. But that feeling afterward? Yeah, that's worth it.

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.

I think everyone deals with things in their own way. Everybody's different. My family are all different. None of us are the same. We all deal with different things in different ways. I think it's about knowing yourself, what pushes your buttons, and figuring out how to work with yourself.

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.

So what if you fail? At least you'll know what not to do when you try again.

If I go down, it's never easy. At least my opponent knows they have to go to the end of the earth to take me out no matter what the circumstances. I do try to compete. Even if it's not your best day, I just try to walk off the court knowing I gave 100,000 percent.
