My favorite struggling writer is the Billy Crystal character in the movie Throw Momma From the Train who spends much of the film trying to write the first line of the book that will free him from his crippling writer's block. "The night was," he writers over and over, never getting beyond those first three words. In the end, comic and harrowing events in his life cause him to throw away the line and just start writing. The lesson is, there is no magic opening line. The magic is what creates the line in the first place.
