Nobody taught Picasso how to paint - he learned for himself. And nobody can teach you to be a producer. You can learn the mechanics, but you can't learn what's right about a script or a director or an actor. That comes from instinct and intuition. It comes from inside you.
Imagine that everything you are typing is being read by the person you are applying to for your first job. Imagine that it's all going to be seen by your parents and your grandparents and your grandchildren as well.
