I don't actually go to that many concerts.

People think I am unemotional because my voice is flat and a bit boring. It is unfortunate but it is just the way it is. I've tried to change it but it doesn't seem to make a difference. The truth is, I have lots of emotions inside. I cried after the semi-final at Wimbledon [2012] because I was proud to reach the final and I knew how much it meant to the country. I cried after the [losing] final [to Federer], too, for different reasons. I felt I had let people down. I think people warmed to that. They could see how much it hurt.

In tennis, it is not the opponent you fear, it is the failure itself, knowing how near you were but just out of reach.

I'd have loved to have been a footballer. I was always playing football and I enjoyed it much more than tennis to begin with. It's more fun to play in a team, all the parents are there cheering you on.

Everything in tennis is so neat and nice but boxing has sport down to its essence; it is very pure and I like that.

Give it everything you've got. Leave nothing out there.

Abiding fully means praying much.
