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 went to Phuket already, but would love to go to Chiang Mai one day.

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.

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.

When you're good at something, make that everything

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.

I am a sucker for those old traditional places, and Rome is as good as it gets, particularly when you throw in Italian food.
