Making it in the film business is best described by the situation when you are a child. When you are playing with blocks they tell you: "Put the square block in the square hole and the round block in the round hole" In order to make it in the film business, you have to get the square block into the round hole. It seems difficult, even impossible when you think about it. Some people quit and don't try. If you grind it hard enough and long enough - it will go in. Don't quit.
