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

The alliance with air Berlin is attractive for me. I can use the whole sales network of the air Berlin and 24 percent of my own airline at air Berlin sold.

Sebastian [ Vettel] can also learn to be more laid-back. It's never too late to learn. He's got some way to go. He's young and will turn out well. I'm not worried about that. He'll raise the bar ever higher.

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.

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!

Grey zones do not interest me at all.
