Birds born in a cage think flying is an illness. - Alejandro Jodorowsky

I think the art of filmmaking is something you learn through actions, by doing it, not by learning theories. And as you do it, your mind starts to change.

At a certain age, you have to make yourself useful for others. When you have lived and life has given you an experience, whether good or bad, the moment arrives when you should pass on what you know. Rather than turn into a dumb old person, you should go further every time. Aging does not exist, neither does mental decline. The memory can have less capacity to find a word or maybe you can feel less sexual desire, less virulence, but there is no reason for desire to have disappeared. If, during your life you have worked the emotions, when you mature you begin to know sublime feelings, which you did not have when you were young because nature did not let you. It takes forty years to find yourself. The true opening of the consciousness cannot be had before this age. From there, the journey begins.

That is the marvel of true art, that no one has yet found a way to commercialize it.
