Just believe in yourself. Even if you don't, pretend that you do and, at some point, you will.

My motto has always been that you can't say, 'Oh, it won't happen to me.' You have to say, 'That can happen to me.' So always be aware that things can happen.

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.

It's a great feeling to have accomplished what I have, but I want to do more.

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.

My motto is: I'm alive, so that means I can do anything.

The thing that's most important in getting you in the best mindest is just being prepared - having a great practice, and knowing that no matter what knowing you're going to go in with confidence. You need to have that confidence to power through.
