I have always felt a little bit uncomfortable with question [why I'm write these stories]. It's not a question that you would ask a guy that writes detective stories or the guy that writes mystery stories, or westerns, or whatever. But it is asked of the writer of horror stories because it seems that there is something nasty about our love for horror stories, or boogies, ghosts and goblins, demons and devils.
Stephen KingLet's get one thing clear right now, shall we? There is no Idea Dump, no Story Central, no Island of the Buried Bestsellers; good story ideas seem to come quite literally from nowhere, sailing at you right out of the empty sky: two previously unrelated ideas come together and make something new under the sun. Your job isn't to find these ideas but to recognize them when they show up.
