I have a Russian heart.

I never think about the numbers. I've never played tennis for the money, because as long as I enjoy it, and I can achieve anything, then the money will come. I know that things will start coming up, many more people will want to start getting involved. But I just want to keep my head cool, and I want to leave (business) to the people who take care of business. I just go out and I just play tennis.

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.

When you come off the court and you feel like you were losing the whole match, and all of a sudden you pulled it out, you know, it's those moments that you feel you've trained for and you work hard for. Just lucky to get through.

It's pretty hard being a tennis player and Mother Theresa at the same time and that's just the way it is.

To be honest, everything in my life outside of tennis is great. I'm doing amazing projects that, if I didn't have time off, I wouldn't be able to focus on.

I'd like to have a family.
