I'm always on the go. I love doing things until I hit rock bottom. Then I need my 12 hours of sleep, and I'm on the go again.

I'm just a very tough person when I go on the court, and I really don't want to lose.

Sometimes when you're putting the work in it just seems so, so hard, and you never know when that work's going to pay off.

Those are real hard fans. There are a lot of them here. Some are a little bit crazy with their drinking their beers every once in a while. But I love it.

I owe a lot to my parents.

Women's tennis is getting faster and the girls are getting more athletic, so I need to push myself to become a better athlete. I think 2013 showed me, like a few other years how important being healthy is and how I must listen to my body. During this off season I have been a little smarter on how I train and how I treat my body.

If I loved a guy as much as I love my dog, the guy would be in serious trouble because I'm all over that dog, all of the time.
