Oh, my God, I don't think any player can look forward to or expect to a career of so many Grand Slam wins or title wins or being so long at the top of the game.

Tennis can be a very frustrating sport. There is no way around the hard work. Embrace it. You have to put in the hours because there is always something you can improve. [Y]ou have to put in a lot of sacrifice and effort for sometimes little reward but you have to know that, if you put in the right effort, the reward will come.

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.

The crowds are very important for tennis. It makes you play better, but it can also make you nervous and that's the beauty of it.

I'm at the top of my game so, when I win or lose, I don't freak out...I don't think we can call it a rivalry yet. There's just to many great players around.

You know, I don't only play for the record books.

Being a husband is for me as big a priority as being a father.
