I decided at the outset to invest in a fairly broad range of businesses, as I didn't want to get pigeonholed into one sector.

It's difficult to relax on tournaments, even in posh hotels, because you don't know how long you will be there - whether you'll lose a match on the first day and leave or whether you'll stay for longer.

You have to go into each match believing you can beat all of the players.

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.

Every week I'll be spending money on flights, accommodation, stringing and even things as simple as taxis, meals out and, of course, paying the other members of my team. I'm still very careful, though, with what I'm spending.
