I'm never satisfied. I'm always trying to get better and learn from my mistakes.

Every day when I get on the floor I give it my all and play because you never know what tomorrow holds.

I've always had to prove myself to people growing up. I had to show them that I could do this and I could do that and paying no mind to what the critics said.

I always want to become better. If never being satisfied is a problem, then I have it. At least it's a good problem.

As tennis players, you are never satisfied. We are greedy as players, always want better results.

Messy stuff irritates me. I don't like messiness. If you leave something around my house, I'll tell you to move it back, clean it up, throw it in the trash - don't matter, just get rid of it. I need stuff neat, organized. And once I start cleaning stuff, I don't stop until it's done. Otherwise I'm irritated all day.
