What I never overcame is a kind of shyness.
I can go in front of an orchestra. I can go in front of an audience. But if you see me walking through an audience in the reception or through a lot of people, I'm still shy.
You know as I started as a shy young conductor, I always wanted to cooperate. To build up the musicians. To help them to be better than without a conductor. And sometimes young talented musicians have to be encouraged.
