I was pretty young when I bought my first place, and at that time didn't really view it as an investment. After living there for a few years I decided to move out of London, so I decided to rent it out for a few years. Then, as the property market continued to rise, I made the decision to sell.

I believe you should give 100% on the court, so I chase every ball.

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.

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.

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.

You are always talking about yourself and tennis and how you are feeling. I try to avoid it when I don't have to.

I've always been a good returner since my junior days - I don't know why that was.
