There are as many ways to begin your book or screenplay as there are ways to procrastinate. Beginning to write your story is easier than you think. All you have to do is sit down, get out a sheet of paper, and give yourself permission to write poorly.
It is not an intellectual exercise. Contrary to what you might think, there is nothing to figure out. In fact, beginning your story is about discovery; you can’t know it ahead of time.
To outline is to begin your story.
To write a character sketch is to begin your story.
To imagine two characters in relationship to each other is to begin your story.
You are much closer than you think.
