To make great art, you need to have an open mind. I’ll give you an example of such an open mind. I read this story in Andy Warhol’s Philosophy, or it might also have been his Popism. I don’t remember but let me paraphrase it for you: “I have a problem,” Warhol said, “something is wrong with me. Every time I watch a detective story on TV, although I’ve watched it several times before, I always forget who’s the murderer.” Of course, there was nothing wrong with Andy Warhol. I think this story is an excellent example of an open mind: it doubts what one thinks one knows so that it opens up to possibilities: the murderer could always be somebody else.
