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.
To understand the intensity of driving an F1 car, you have to be in it. When you're driving a 750hp machine at 200mph, 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.
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.
We go through the whole season working on next season's car and developing the car and making sure we fit in the car and all that sort of stuff. And we obviously give ideas of what we would hope next year's car would have even if it's small things like buttons on the steering wheel and different positions and whatever.
That Monaco crash was quite a big one - I pulled 33g when I hit the wall, which is a lot. It's a weird sensation - like all my skin and flesh was being pulled off my bones.
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.
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.
I have made lots of mistakes in terms of contracts and spending money when I shouldn't have spent money.
We all drive differently and have different styles. For me I need a car I can develop beneath me and feel comfortable in. If the car feels neutral and unbalanced it doesn't work for me.
I don't purposely speed, but I might go over by five or six miles an hour from time to time. It doesn't give me a buzz driving on normal roads, because I can't go fast enough. It's never going to be anything like an F1 car.
The only time I think about life beyond F1 is when I contemplate becoming a dad. But there's no way that's going to happen while I'm still racing. To be successful in F1 you need to be very selfish in lots of ways and you're away from home for long periods. That's not the kind of father I want to be.
It is such a special feeling to win a grand prix.
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.
