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.

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.

If I ever have a son, and if he wants to follow in my footsteps in Formula 1, my main responsibility will be to point out some of the negatives.

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.

I keep my weight low, although you need to be able to move your weight around the race car to change the balance. I'm 6ft and I'm 70kg so I haven't much fat on me.

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

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.
