The secret to the movie business, or any business, is to get a good education in a subject besides film - whether it's history, psychology, economics, or architecture - so you have something to make a movie about. All the skill in the world isn't going to help you unless you have something to say.
But having a really good understanding of history, literature, psychology, sciences - is very, very important to actually being able to make movies.
Before I became a film major, I was very heavily into social science, I had done a lot of sociology, anthropology, and I was playing in what I call social psychology, which is sort of an offshoot of anthropology/sociology - looking at a culture as a living organism, why it does what it does.
