From success, you learn absolutely nothing. From failure and setbacks conclusions can be drawn. That goes for your private life as well as your career.

You must always aim for further growth.

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!

If you are a straightforward racing driver you should always see your limits. You have to be objective and not come up with any bullshit.

To be honest, it is boring to talk about winning.

I was not interested at all in Formula One when I left; I was very busy with my airline. But slowly I started missing the adrenaline rush and the driving of such fantastic cars at the limit. In reality this urge never disappears when you're a top driver, because I think we're a different breed of people, we need to take chances, we need to push ourselves to the limit all the time, that sort of thing. It stays with you, although you can kill it by losing motivation or other things in your life, but it never leaves you forever.
