When I can’t understand something important, I search, I research and I write. I write and write everything I know, everything I feel until clarity comes. Sometimes I don’t completely understand until my story is told. Sometimes I don’t understand the details even then.
What is a draft if not telling yourself the story. Rewriting and editing are for clarifying it all first in the mind of the writer so that the reader may ask the right questions to find their own answers.
