Here is a simple method of deciding on the subject matter of your book. Write down what you enjoy, want to learn about yourself, what you already know and what you are good at in the darker crescent. In the lighter crescent, list the things you want your readers to learn when they read your story. In my first book, I chose to teach children ages 4-8 about the water cycle, being a good friend and how important it is to be patient! Those are items I would list in the golden spot.
This can be really helpful to keep you focused and on the right track as you write your story, paint your picture, plan a curriculum lesson or complete a journal entry. If your brain runs like mine, I can go off on way too many tangents and need a visual to bring me back to golden spot.
So, create your own Venn Diagram and write the first sentence!
