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.

You have to believe in the long term plan you have but you need the short term goals to motivate and inspire you.

The serve, I think, is the most difficult, you know, in terms of coordination, because you got the two arms going, and you got to toss it up at the right time so.

Clearly, when you win everything, it's fun. That doesn't necessarily mean you love the game more.

Mentally, I'm not ever going to go away.

I haven't had a cramp since '99. That was my only time, in Davis Cup, when I was panicky. I was young. I'm very proud of that. Never pulled out. Never had cramps. Never lost very much because of fitness, especially later on in my career where I knew I've put in the hard work. I've done that. I've been very fortunate and clever as well to understand how I need to work, when I need to work. So I'm very happy to have stayed injury free for so long. I hope I can still maintain a few good years on the tour. I really hope so.
