This prompt comes from The Right to Write: An Invitation and Initiation into the Writing Life by Julia Cameron (pgs. 25-26).
Set a timer (see below) and write...
Perfectionism is a primary writer's block. We want to write--we just want to do it perfectly. With this tool you will deliberately indulge in some "bad writing."
Step one: Buy three tabloids (e.g., National Enquirer, The Star; if you cannot find tabloids, buy People or Us). Scissors in hand, read your tabloids. Snip out ten stories that strike you. Clip your stories together and save them in a file folder. Did you notice any common denominators in the stories that interested you? Were they upbeat or downbeat? Weird? Kinky or heartwarming?
Step two: Set aside one half hour. Writing as fast as you can, longhand, write a make-believe tabloid story. Make up characters, incidents, and quotes. Be outrageous. Meet and marry aliens from outer space. Discover your long-lost twin. Survive a grizzly attack. Win five million dollars. Write boldly and badly. Scribble this story off. At the end of one half hour, stop writing.
