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.

When I'm on my own, I can be negative. I need my friends and family around to help pick me up if I've had a bad qualifying session. I think insecurity plagues a lot of sportspeople.

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.

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.

I have made lots of mistakes in terms of contracts and spending money when I shouldn't have spent money.

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.

My 'Movember' moustache was never going to be as big as Nigel Mansell's, but I tried my best. The amazing thing is that when you try to grow a moustache, you notice everyone else's. There are some amazing moustaches on the grid.
