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.

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'm trying to keep my personal life personal. It's very hard for me because I'm a very honest person.

Generally speaking, the people who come to work at Snapchat believe in personal growth. It's part of why Snapchat's stories are ephemeral, because you will be a different person tomorrow.

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.

You're definitely a different person at different stages in your life.
