I'm so frugal, you wouldn't believe it.

I love hitting aces. It's not easy, but it makes your life a lot easier.

I'm a high-performance athlete: I'm running, I'm sprinting, I'm sliding, I'm doing pretty much everything and the last thing I want to worry about is my chest. I want to just worry about playing the sport at the highest level that I can.

I really think a champion is defined not by their wins but by how they can recover when they fall

Who says that your thirties is when you're supposed to be done? I would like to know who made that rule!

I've developed a karaoke habit. I've become a crooner.

If you can keep playing tennis when somebody is shooting a gun down the street, that's concentration.
