In the winter I was with Nelson Piquet. He was talking about his capacity to race faster. He said that he was still learning new things all the time.

You tend to think that there is a big gap between F1 and everything else. F1 is where all the fantastic drivers are, so you just don't know how good you are until you get there.

I had a very good package for Phoenix, but at other tracks we do not have the power. The Brazilian Grand Prix was maybe closer to the reality.

I am a professional. At the circuit I am calm. At home I am very different.

I am not close to retirement. I still have a lot more that I can achieve. There are younger guys coming into F1, but I am not old and I'm not finished.

Experience has taught me that you have to improve all the time-little bit by little bit-and not keeping starting everything from new.
