A talk show is scripted to promote the guest and discuss topics with which the guest is comfortable. Imagine your protagonist on the Ellen Degeneres Show (or The Late Show With Stephen Colbert - whichever show you're familiar with). What questions would be asked of your protagonist? What funny anecdotes would your protagonist share? Write down the reactions of both your protagonist and the host.
There's a saying: "Everyone is the hero of his or her own story." For a 10-minute writing exercise, enter your book from another character's eyes. Think about how differently that character would experience your plot and capture that in a short story.
Develop your characters by placing them in a situation where they are faced with a challenge. For conflict inspiration, look no further than these classic moral dilemmas (and, of course, analyze them from the perspective of your character). For an example of a moral dilemma, search "The Trolly Problem."
Write a pivotal scene in your novel from a different character's POV. For instance: at a funeral, you may have written the grieving widow's thoughts and feelings. Write about that funeral from the deceased husband's POV, the eldest son's, or the step-sister's.
Select a scene that involves 2-3 characters. Write a paragraph from the point of one character. Now write the same interaction from another character's point of view. For example: your paragraph could involve the point of view of a convenience store clerk contrasted with a customer's point of view of the same incident.
