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

One of my big, big strengths I think early on in my career was that I could learn very quickly. You wouldn't have to tell me the things 10 times or 50 times until I would understand them. You would only have to tell me two or three times.

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've always been aware that the image you patiently construct for an entire career can be ruined in a minute. It scares you a bit, but that's the way things are.

There is no way around the hard work. Embrace it.

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.

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