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.

Well, my mum's been a tennis coach - she coached me till I was 12.

I've always been lucky enough to just play tennis, so I never actually had a job when I was growing up.

I try to anticipate the ball well. That's something that's helped me since when I was a kid. Just learning to anticipate and read the game well. That's helped me. When I moved over to Spain and I was 15 I was playing with big guys who were 22 years to 28 years old and I was 15 so I couldn't beat them with power. I had to beat them with touch shots and variety and anticipation and all of those things. I learned a lot when I was over there.

I think it's sensible to plan for the future now I'm a father and a husband.

As a child I was a good boy. Even if I wasn't playing tennis I don't think I'd have done things like smoking or getting drunk. I'm lucky I never liked the taste of alcohol - I know, I'm Scottish so what's wrong with me? - but I never even liked the smell of the stuff. It's the same with smoking, it never appealed to me. I guess I missed out on my Kevin-The-Teenager phase.
