Each piece of writing needs a Central Dramatic Question which has a yes or no answer.  For part of my book - and my life - the Central Dramatic Question is:  "Will I find a career that is personally and financially rewarding?" 
There needs to be an overarching Central Dramatic Question for the book and a Central Dramatic Question for each scene.  I started to write a series of scenes that went to the overall theme of the book and to think about each individual Central Dramatic Question.
Because I was only structuring today and didn't produce any new work, I read a text about how I coach and why I love my coaching clients.
