Jazz saxophonist Stan Getz took a teaching position at Stanford in 1986. In an interview with a reporter about his role there, he put it this way:
I’m a strong opponent of imitation. I always tell them that they have to be themselves. That’s hard, because they don’t believe in themselves, they believe in their heroes. And I will tell them: that’s perfectly alright, but your hero is the only one who can play that way. If you want to try and do the same thing, it will only be an imitation, however perfectly you will do it. I keep on trying to convince them that they have to play what they feel themselves. But that’s not easy.
Your hero is the only one that can play it that way. Be yourself.
