The serve, I was too young and too small and... not enough powerful to have a good serve when I was young, so my forehand was always my signature shot. So I used to always run around my backhand, you know, use my forehand as much as I could, and so that's why I think it's my strength also today, you know.

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.

The one thing you can do for sure is push the luck on your side

I have a great record against anybody right now, so it doesn't really matter who I play in the final. I'll be in there as the big favorite. But I play my best in the finals, in the important matches. That's why I'm number one. There's no secret...I'm not overconfident, but very confident.

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.

No, I'm not (disappointed). There's no reason to be because I'm on an incredible run. You always expect a loss once in a while. So when it happens, why be disappointed if I win over 90% of my matches.

The more I lose, the more they believe they can beat me. But believing is not enough, you still have to beat me.
