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 guess the closest I came was doing chores around the house to earn pocket money. My brother and I would have to do the washing up, cleaning around the house, walking my grandparents' dog, lots of things. We didn't get a huge amount but it was always enough to be able to walk down to the local shops and get some sweets.

I bought a Ferrari...and then sold it after a couple of months.

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

I've never felt nervous in front of big crowds and in big stadiums.

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

I had to pay an incredible amount to get insured on it and, after a couple of weeks of driving it around, I realised it wasn't quite my style. I'm not flash by any means but a bright red Ferrari is a definite head-turner and I hated that. It was also incredibly impractical, particularly when it came to finding space for a friend or for my tennis bag, so I decided to sell it after a few months.
