I always knew I had something special.

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.

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.

When you're good at something, make that everything

You always want to win. That is why you play tennis, because you love the sport and try to be the best you can at it.

When I think of the Olympics I only think of good things. I think of what a great event it is and what it has done for me and my career, and changed my personal life, too.

I have learnt to be even more patient.
