As you write your story, edit, edit, and edit some more — others themes and story thoughts will come to mind (did for me at least) – WRITE THEM DOWN. Be as detailed as you can in the outline because these will be your future stories.
I had fun with this one, and am excited about the book I write after finishing “I Am Archon” and “Causality”. It is actually nice to have goals beyond just the one book.
