In Bird by Bird (Pantheon, 1994), Anne Lamott's classic instructional treatise on writing and life, the author says: "Writing a first draft is very much like watching a Polaroid develop. You can't—and, in fact, you're not supposed to—know exactly what the picture is going to look like until it has finished developing." Keeping this in mind, write the beginnings of an essay whose direction and ending you don't yet know. Start small, focusing closely on a single place, person, or incident, without thinking ahead. Then keep going: Allow the writing to tell the story, and see what develops.
