Really, you should always discuss the defeats because you can learn much more from failure than from success.

Taking your first title is much more complicated and more difficult; it takes years of work - from go-kart to Formula One. The second comes more easily, because you've already got the experience.

If you are for a long time at the top you've basically achieved everything you wanted to. Then the ball's breaking stuff starts to be too much: it's not what you do in the car, it's what you do outside the car - the press conferences, the interviews, the sponsorship commitments, the marketing appearances - that sadly go up to a level that the whole package, including the risks you take, the workload you do to get the car to work and for you to be quick in the races, it becomes too much.

Ultimately, an aircraft owner does not want to have to deal with all the intricate details which are necessary for the business.

I am someone who places great value on the detail. That was always the case, even in my days as a racing driver.

You have a brake in your brain that stops you doing stupid things. The older you are, the earlier that brake comes on. When you're 20 you stop at nothing; when you're older you're cleverer than when you're 20, so your brain brake operates more often!

I always go extreme ways.
