Once I defined the questions, I wrote in sprints without correcting grammar or spelling to answer each of the questions. Sprints were a few minutes, not more than 5.
When I answered all of the questions I would go back and remove the questions and edit for flow and add references and supporting facts. Last would be a grammar check, but I relied on my editor to review that given that I was often writing on deadline.
I produced more than 200 articles of 800-1000 words. Week over week even when I had writers block or no desire to write at all.
