I retired simply because I didn't have the passion and motivation anymore, I was tired. At the time I thought, 'Well, I had a great time, there is the end.' At some moment there is the right time to call it an end.

I have what you might call the South Pole and the North Pole. I have my team and my work, which I do on one side, and I have my family and my home on the other side. Both have nothing really to do with each other.

I hate to take compromises with a racing car. The more standard a car is, the more compromises you have to take.

I like to share my life, and spend time with someone I love. That has worked 100 per cent with my wife.

When you're very successful, you become careless and try to turn many things into routine.

In sport there is never any moment that is the same as the other. I have been in Formula One for 12 years, and out of that I had one year with the perfect car.

Psychologically speaking, it's very important to be in good shape. I work in a sport that requires you to react quickly and be in excellent shape. Besides, things don't get easier as you get older.
