The mistake I really learned from was in 2005, leading the Indianapolis 500. I had a decision whether or not to save enough fuel to finish the race - which meant slowing down - or going all-out for the win. I went conservative and saved enough fuel to go to the end but finished fourth.

I know that England changed me. I became a little bit colder, a little different.

Sometimes it takes looking at the past to really be able to move forward and learn from it.

My boyfriend loves golf and he is good at it but I am not that great at it. It drives me nuts, but I'm super competitive and I always want to win.

I think you have to feel comfortable with your car. You have to go into Turn 1, every lap, with confidence. You have to be sure of yourself and your equipment.

I think you can be happy and still be competitive. A good lesson for everybody is to think a bit before you speak and represent who you really are instead of the brash emotional you.

I've never been bashful to say that I'm not really interested in Formula One. When I lived in England, it's all I wanted to do and I thought that anything else would somehow be a compromise to my dreams. But then when I came back to the States, I realised how much I loved being back in the States...
