When it comes to my racing career I'm very driven and very selfish. People who are around me at races will know that I'm a different person here than in my personal life. I completely blank people at races. I need to be focused. I'm rude.

I always sleep really well, particularly before a race, when the adrenaline's pumping.

To drive an F1 car you have to be a little mad. On the morning of a race there's a mix of excitement and fear. If it's a wet track, then it's worse as you're not in control most of the time, which is the thing all drivers fear the most.

The fast, flowing parts, the high-speed corners, that's where a Formula One car is at its best - changes of direction, pulling high g-forces left and right.

I don't purposely speed, but I might go over by five or six miles an hour from time to time. It doesn't give me a buzz driving on normal roads, because I can't go fast enough. It's never going to be anything like an F1 car.

When I was in Japan with my girlfriend Jessica, she would have had acupuncture every day if she could. I can just about stomach going to a chiropractor and I visited a talented one when I was there, but when he tried a needle on me, it was horrible. My muscles tightened and it didn't work at all.

It doesn't matter who wins if I don't. I only care if I win. I'm jealous of anyone else who wins.
