Former director of the UCLA writing program, Atchity was one of the first to detail a two-part process of book creation. Natalie Goldberg delivered the first step in her “freewriting” exercises in Writing Down the Bones. Atchity took it further. Since books demand two sides of the creative self, he proposed, both the random and linear, freewriting lets us craft random “islands” of writing. Then when we’ve created sufficient “islands,” we form them into continents via a storyboard.
If you get the chance, read A Writer’s Time -- it will change the way you think about writing.
