It's a passion when you're doing it for other people and you're doing it for the people around you making the film and the people who are going to see the film, and the giving. When you start thinking about you doing it for some sort of self-gain, then I think it becomes an obsession. It becomes a negative experience.
Stanley KubrickThe test of a work of art is, in the end, our affection for it, not our ability to explain why it is good.
