It happens all the time. But it's depressing. My aim is to help kids realize that they're artists already, or that maybe they don't really want to do it, which is more than fine. They've saved themselves a lot of grief, and they can get on with their lives. I tell them that I'm not interested in educating their minds, I'm interested in sophisticating them, which is different.
Sophistication is knowledge that's acquired in the course of having a purpose.
You know why you want the information at the moment that you put your hand on it. You're not just storing it up for a rainy day. You're learning about the course of art, the course of society, the course of the world, the course of your life. You are joining a conversation. You do not prepare to join a conversation.
