My dad said if you become a tennis professional just make sure you get into the top hundred, because you have to make a little bit of money. You make a living so you can pay your coaching and, you know, your travels.

I'm playing great tennis. I'm enjoying the tour, having fun with the fans off the court. I'm loving it now.

Confidence? Are you kidding me? I mean, please. Look, some players grow up and play like that. I remember losing junior matches. Just being down 5-2 in the third, and they all just start slapping shots.

Early in my career, I struggled with consistency, but I couldn't get more consistent than this year.

It doesn't need to be the same every day, doesn't need to be the same shower I use, the same restaurant I go to, the same hour I go to sleep. I've always been very flexible. I don't care if I practice at nine in the morning or 10 P.M.

I have a very strong opinion. I'm absolutely against it. I'm against the challenge system. I'm for the way it is right now. Don't change that.

I always believe if you're stuck in a hole and maybe things aren't going well you will come out stronger. Everything in life is this way.
