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

You look back and you remember the good, the bad and the ugly

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

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.

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.

If I run I lose so much weight, which I need because you're limited on weight when you are a tall driver. And have you seen marathon runners? They're quite skinny.

In the car and in front of the camera I tend to be very calm but behind the scenes I can get fired up and passionate, I just don't see the need to shout my mouth off in public.
