I'm not the kind of guy who wakes up angry.

I have two lives, and all the problems I might have, I feel like I drop them once I step on to the match court.

I am a very positive thinker, and I think that is what helps me the most in difficult moments.

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 don't need to come back to Wimbledon every year because I can't live without it. I'd be totally cool without tennis.

My heart is in South Africa, through my mum. My mum being from here, me spending a lot of time here as well, I feel most connected to this part of the world.

I am very blessed to be able to play tennis, the sport that I love and very grateful for the opportunities to play in the finals of big events, when the season starts you are on the roll constantly and obliged to be committed to daily routines on and off the court.
