Writers' notes
David Brooks structures geographically: organize my notes into different piles on the rug in my living room. Each pile represents a different paragraph in my column. The piles can stretch on for 10 feet to 16 feet, even for a mere 806-word newspaper piece. When "writing," I just pick up a pile, synthesize the notes into a paragraph, set them aside and move on to the next pile. If the piece isn't working, I don't try to repair; I start from scratch with the same topic but an entirely new structure.
Wonderful described his process in an essay just called "Structure." For one long article, McPhee organized his notecards on a 32-square-foot piece of plywood. He also describes the common tension between chronology and theme (my advice: go with chronology). His structures are brilliant, but they far too complex for most of us. The key thing is he lets you see how a really fine writer thinks about the core problem of writing, which takes place before the actual writing.
