There is an old writing adage which exhorts you to write what you know.
If you have never been a police officer, or investigated a murder, then you might want to avoid crime novels.
Yet plenty of writers ‘do’ crime.
Why? Possibly because they want to murder someone and they’ve really thought hard about it?
Fake it until you make it?
You get out of your writer’s room and ride along with the police and detectives so you do know what you are talking about?
But what do you know that can be used in a different way?
George Lucas knew Westerns and Japanese Samurai movies but he had a fascination for space.
Think about your setting and drop in different characters or point of view.
Think about your characters and drop them into a different setting.
See what happens.
