"...Stories, even ones with jumbled timelines and time periods, are linear. They start, stuff happens, they end. When working out a story, I try to stay away from traditional outlines. Trying to sit down and begin by listing the scenes in order seems overwhelming. My answer is to use notecards that I spread out on the floor. Ideas for scenes go on a card and initially aren’t required to work in concert with other scenes. This process ends up creating connections and story lines that might not have been discovered otherwise. You never know where a card might land on your floor. " -Jeff Nichols
