Five Writing Exercises for Writing Fiction

For writers, there is nothing worse than when the narrative comes to a grinding halt. For some, freewriting is enough to get started again. Others need more directed exercises.

Liar, Liar. Put your character into a situation where they have to choose between telling a lie and accepting some fairly dire consequences and write out what they would do. Do they lie quickly, easily, and without remorse or chose not to tell the lie at all no matter what the consequences? Perhaps they come up with a way to handle the situation without having to lie. This can help you get further insight into your character as a moral being.

Old Family Stories. Family members like to tell stories about one another, not necessarily the good kind either. What kind of stories would your character's mother tell about them if given the chance? What about their grandparents, or best friend? If it is a childhood story, how does the person in the story differ from how the character is now?

Talking Heads. This works as a dialogue/freewriting exercise. Take two characters (protagonist/antagonist, protagonist/sidekick, antagonist/minion, sidekick/minion, you get the idea) and write out what they would say if they were face to face. Let the characters say whatever they want, they might open up subplots you had not thought about or insight into the main plot you had not previously considered.

Letter to the Author. Step into your character's shoes and write out what they would tell you about your story in the form of an editorial letter such as you would see in the newspaper. You can even use the character to predict what is going to happen next from their point of view. This is their chance to give you their opinion of the story. (Examples from the National Novel Writing Month forums.) This is actually my favorite exercise.

The Other Side of the Story. It can be really difficult to incorporate a second person's viewpoint into a narrative, especially if the person in question is the antagonist. However, it can be useful to know exactly what your antagonist thinks about the situation. Take the time to write out a section of the story from the point of view of the antagonist. Give the character a chance to muse on how they would have handled a situation differently if they knew then what they know now, since this section of the story has already passed.
