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

My advice is you've got to make sure you wear the clothes and not [let] the clothes wear you. It's quite simple in a way. Don't wear something you totally feel uncomfortable with, but take some chances. Play around a bit. I felt very uncomfortable in suits when I was younger, so what I just started doing was wearing suits when I was going to dinner. I used to overdress a little bit so I got used to wearing suits. Now wearing a suit is like wearing a track suit for me. So it's all good.

I used to get nervous, you know if my parents would come watch. And then I would get nervous if my friends came and watched. Today it's not a problem anymore actually, because now I enjoy it. I see that they, you know, respect me immensely, and I try to put on a good show and show that I can still play very good tennis.

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.

It is always in my mind still that I can crush anybody. That's not an issue. But I think that is the same for most athletes. If you don't believe you can win tournaments anymore, then you can't do it.

I love tennis! I've always felt like this because it is such a classy sport with a great, competitive flair to 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.
