I believe I live in a black and white. I think things are like either black or white. I don't really believe that much in the gray. I think that there's gray for a lot of people, but I don't live in the gray. I realize whatever action I have or take, it's going to have a consequence -- either good or bad. So I live my life in a way where I don't have bad consequences. I just notice there's a lot people around me just live in the gray. I don't know, for me, I'm just really straightforward.

Life is challenging but I'm always up for a challenge.

I just try to stay positive and focused on the tennis, not let anything get to me, like crazy questions. But I'm tough, let me tell you, tough as nails.

Just always believe in yourself. "Champions adjust." It's a line I learned from Billie Jean King, and sometimes your dream adjusts. Be willing to adjust with it and see where your opportunities ... sometimes a door closes but a window opens, so just follow your dreams and continue. You never know where it's going to take you.

In the sports arena I would say there is nothing like training and preparation. You have to train your mind as much as your body.

You learn so much from your parents. We grew up in a home where we were definitely taught to be confident. I definitely give me parents a lot of credit.

A win's a win, unless it is not a win, and then it's not a win.
