The Character Interview as a Writing Tool
When writing a novel it is important to know your characters, and it makes life easier to get to know them early in your writing. There may be things in your character's past that you will not write in your book, but will still influence how the story plays out. One way to glean this information is to interview your characters and ask them some questions about their childhood, events or people who made an impact on their lives and their present circumstances. Ask all your characters these questions and let them answer in first person. Free write what comes to mind without self-editing. You can add questions of your own.
