I have always written out of order. I usually know the last scene before I know the first, and I tend to carry two or three versions of the same moment in my head at once. For years that made me feel like I was doing it wrong, because outlines are these neat straight lines and my head is just not a straight line. What finally helped was to stop forcing the line and let the story be a map instead. I lay every beat out where I can actually see it, let scenes branch into alternate versions so I do not lose the one I did not pick, and I keep the references and the characters and the places right next to the words. Seeing the whole thing at once is the only way my brain holds a story. I ended up building a little free thing for myself to do this, and I give it away, but honestly the tool matters less than the permission. If you also think in pictures and out of order, you are not doing it wrong. Curious how the rest of you hold a whole story in your head. Do you outline in a clean line, or is yours a beautiful mess like mine?
