Tip #295: Is your theme a question?

instead of using the theme “justice,” let the events of the story pose a more engaging question: “What’s more important, telling the truth or protecting the innocent?”

Rather than giving the advice, “You should forgive others,” let your story explore a dilemma: “How do you forgive someone who has done the unthinkable to someone you love?”

Let your story do more than reiterate the cliché, “The needs of the many outweigh the needs of the few.” Instead, challenge that axiom by presenting your characters with situations that raise the question, “When do the needs of the few outweigh the needs of the many?”
