I know my boundaries. I know the limits to the car.
I enjoy trying to develop a car and Mercedes are one of the biggest car manufacturers in the world.
I was trying to control myself because I wanted to just park the car and jump out and do cartwheels. The next dream is to win the world championship.
My brother and I are always playing F1 on the PlayStation and now I am going to be in one of those cars on the games!
Nothing can really prepare you for when you get in the Formula One car. Knowing that you're driving a multimillion-dollar car, and if you crash it it's going to cost a lot of money, and they might not give you another chance, is scary.
I'm constantly watching my weight for my job, and I've trained so hard this year to be ready for this season-more rigorously than ever - but people who tune in to Formula One have no comprehension of what we have to do to be fit. It's so physical. This year, the car is way faster than when you came to the race. And the physicality has gone up quite a lot, at least 20 to 30 percent. People don't see that. They don't see us as athletes. They just see us driving.
Now each race is different every time because it's a different journey to get to it - the difficulties you faced getting the car into that position. I manage myself. I chose my team myself. So there's a huge satisfaction for me.
My brother was told that he wouldn't walk, that he wouldn't be able to play drums, that he wouldn't be able to race a car - and he's done all those things. He's defied the odds, defied disability. I look at him and I'm so inspired, by his mentality and by how incredible the body and the mind are. There's really nothing you can't do. My brother has proved that.
