Do not quit. You see, the most constant state of an artist is uncertainty. You must face confusion, self-questioning, dilemma. Only amateurs are confident … be prepared to live with the fear of failure all your art life.
I have an ambition to live 300 years. I will not live 300 years. Maybe I will live one year more. But I have the ambition. Why you will not have ambition? Why? Have the greatest ambition possible. You want to be immortal? Fight to be immortal. Do it. You want to make the most fantastic art or movie? Try. If you fail, is not important. We need to try.
You have to be like a poet. Your movie must be just as you think of it and just as you want it. Do not take comments to change this or that from this person or the other. No! The movie has to be just like I dream it. The picture needs to be exactly as I am dreaming the picture. Is a dream. Don’t change my dream.
