Linda Holmes: Hey, Kid: Thoughts For The Young Oddballs We Need So Badly (NPR)
Learn the difference between feedback and criticism. Feedback is primarily for you; criticism (in the sense of "a movie critic" or "an arts critic") is primarily not. Criticism is part of an ongoing cultural conversation that's designed to make everybody smarter and better and more thoughtful and to advance the art form itself; it's done even when the creator of a piece is long dead. It's not really for you.
Feedback, on the other hand, is aimed at you to make you better, and that's the only kind of feedback worth paying attention to. If you can't listen to it and take it in without your hackles rising, you will never become good. Period, boom, g'bye.
