The public want actresses, because they think all actresses bad. They don't want music or poetry because they know that both are good. So actors and actresses thrive and poets and composers starve.
They will always tell you that you can't do what you want to do, but you can do what you want to do. You just have to believe in yourself. The system is to bring you down, but you can rise up.
You have to decide what is extraneous and what is central. There is always more to tell. If you want to have a finished product, at some point you have to say "enough."
