I have to fit holidays around tournaments, particularly the grand slams, in Melbourne, Paris, London and New York.

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.

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.

I used to do a lot of video analysis early on, but more for pleasure and looking at my own technique.

Obviously, matches and all that stuff takes its toll on your body and so forth. But as you get sort of a bit older, a bit wiser, and a bit more experienced, you know also how to handle it.

I'm not angry. As an athlete ... you should be open to criticism, and you're allowed to be criticized, because not everybody has the same opinion, not everybody likes the same players. The rankings are quite volatile: Today you're 'great,' tomorrow you're 'not,' but then you're 'great' again. It makes for great stories. Now, I always look at the long term and by doing that, obviously, I can stay calm through the storm.

When they [court announcers] say, 'This is the world No. 2,' it just doesn't sound right to me because either I'm No. 1 or I'm a grand slam champion. I'm not world No. 2. I just don't like the ring of it when I'm introduced on court because I've been up there for so, so long.
