My father did everything for me. He was awesome.

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.

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

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.

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.

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 need to develop a car and engineer a car in a position that feels comfortable for me, and I don't think anyone can do a better job than I can in that position. The problem for me is if I can't get the car there I do struggle more than some.
