I always think I should try to get to bed early, but then I can't stop myself from watching telly and fiddling around on the net.

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.

My school reports always used to point out that my concentration levels were appalling. I never listened in class because I was always daydreaming about racing. I never thought for a moment about doing anything else. There was no guarantee that I'd make a career in it but I never had any plan B.

When I do retire, I know for a fact that I'll never be able to replace the incredible feeling I get when I'm driving an F1 car.

To understand the intensity of driving an F1 car, you have to be in it. When you're driving a 750hp machine at 320km/h, the noise and the vibrations are incredible. The G-force when you take big corners is like someone trying to rip your head off. You hit the brakes, and it feels as if the skin is being pulled off your body.

It doesn't matter how much money you've got, or how many connections, there's always something you want that's out of reach.

When you're in a car which can win every race, or fight for a win every race, that is pressure.
