I always have a Sharpie, because usually when someone asks me for an autograph, they don't have a pen. I carry one in my purse, as well as in my tennis bag.

I had so many outs in my career. I could have said, I don’t need this. I have money; I have fame; I have victories; I have Grand Slams. But when your love for something is bigger than all those things, you continue to keep getting up in the morning when it’s freezing outside, when you know that it can be the most difficult day, when nothing is working, when you feel like the belief sometimes isn’t there from the outside world, and you seem so small. But you can achieve great things when you don’t listen to all those things.

I love to collect modern art.

I don't spend a lot of my time in the locker room. That's my least favourite place in the world.

Tennis has never been the most important thing in my life. My family, my health, my happiness...they are more important to me. On court, I want to win. Off court, I want to be a better person. Tennis is a path to my future.

It's strange for my friends when they see me on TV and in magazines, because the person that they see doing interviews and pictures on the red carpet is not the person that they know.
