The crucial point is always the own cost structure. Therefore I created a Low Cost alliance with air Berlin.
I'm really focused when I'm working out, so I don't really listen to music. I like to listen to music after, because it's like, 'Yeah! I finished! Let's party!'
As long as I'm still able to have a hit on the radio and sell a few albums and some tickets, I don't see that it would be worth retiring.
