For me, by far, the Olympics is the biggest sporting event in the world.

I proved that I can win the Grand Slams. I proved that I can last four and a half hours and come out on top against one of the strongest guys physically that tennis had probably seen especially on this surface.

I was playing in the juniors at Wimbledon I forgot to turn my mobile phone off. It was lying there in my bag and it rang in the middle of a match, and it was one of my friends from school saying, 'Murray, you're on the telly!' I learnt from that. I now put my phone on silent.

Obviously you try to keep as much of your private life as private as you can.

I'm a global ambassador for the World Wildlife Fund and United for Wildlife and I am also a Unicef UK ambassador. It's important to me to support charities. I never want to take my wealth for granted.

Davis Cup, you know, does take a lot out of you over the weekend. It's tough, especially if you play all three days.
