At the start of your writing time for the day, jot down three ideas that interest you. Then pick the one that most interests you. Close your eyes and imagine it as a movie playing inside your head. What happens? Write about what took place inside your head.
Instead of a topic you can do this with a character. In this case, close your eyes and picture the first person that comes to mind. Describe this person and then plop him/her into a setting and see what develops.
In either case, let the images flow on their own and write down the result in your movie/writing journal.
My movie journal entry for this exercise is based on an image of an angel coming to my mind.
Angels and Children – Tommy is a junior angel. His eighth birthday was just around the corner when he was called back to heaven. That was a year ago. His first assignment starts when a young mother prays for her six-year-old child who is starting school the next day. Tommy must help the handicapped Patrick as he navigates the strange, new environment without friends and hiding a handicap. Quite a first assignment for a junior angel.
