When you are a leader, you have to learn how to work because you have to convince the people in front of you of your ideas. When I started to conduct in professional orchestras when I was 22 or 23, [I had to] convince people with a lot of experience, with the tradition of sound or the idea of specific piece. What I want from the musicians is to enjoy what they are doing.

-Gustavo Dudamel
