What waits at the end of the journey?
Collect your thoughts and your words. Create a character and a story inspired by those thoughts and words. Make it a whole story, a scene from a screenplay, a synopsis, any format that pleases you and allows you to unleash that monster (The Writer) in you waiting to get out.
