I believe one of the important differences between creating literature and just telling a story around the campfire is that in literature you’re recreating the experience of life, not just relaying a ‘this happened, then that happened’ kind of narrative. The specific details and layers of depth that make the world of the story — and what the character is experiencing in that world — as real as possible are elements I love as a reader and, consequently, elements I strive to use effectively as a writer.
