Tennis is a huge part of my life, but I don't base my self-value or my self-worth or the quality of my life on my results on the court.

Grand Slam losses are hard. I treat myself after losses though, I usually go to McDonald's and I have a hamburger and you know, something. Because you know, you just need to be nice to yourself sometimes after the loss.

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.

When youre on top, youre on top.

I don't want to give anyone an edge in my mind. Every time I walk out on the court, I have to feel I'm the best so I can compete well. A lot of times, my chief rival is just me.

Sjogren's is something you live with your whole life. The good news for me is now I know what's happening after spending years not knowing... I feel like I can get better and move on.

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