2. Write in scenes: diagram them first
One of the challenges with fiction is logistics; moving people around in your scenes. Two people in a scene are manageable; more than two are a challenge.
Before I start a scene, I like to draw little diagrams on index cards. I identify each person in the scene, what his or her goal is, what secret they’re keeping from the other characters, and anything else that’s important.
When you think through a scene before you start writing, your writing will flow, and you’ll write more.
