It is very important not to think about losing.

I have a lot of dreams, and most of them come true these days.

Id like to imagine that in order to beat me a person would have to play almost perfect tennis.

I don't come to tournaments to make friends, to go to parties, to hold conversations. I come to be the best, and I'm not mean and cruel and dirty.

A lot of people say, "Oh, I get this high from working out." I've never felt that, maybe because I've worked out for so long it's just a norm for me to push super, super hard. I don't feel the euphoria. But at the end, when it's all done, I feel euphoric. I'm like, "Yes, the work is done." You just feel like a glowing feeling inside.

I don't carry a purse when I fly because I have my Hello Kitty carry-on. I'm the biggest adult supporter.

I guess it's a little bit sentimental, but at the time I was really very focused in on really my performance. Afterward, it was really just a breath of fresh air, just like, 'Oh, yes, I'm back now. I'm doing good.'
