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 getting consumer reports. I think it's one of my favourite things, studying what people have to say about the product and then trying to make it better.

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.

My next goal is to be number one in the world.

When you are young, you are a little naive.

I'm always that annoying person that pulls out the camera in the middle of dinner and starts taking candids.
