I disagree as well. You put it raw onto the page and rework it until its right. A story tends to write itself and you just have to continue to evolve with it, making adjustments and changes as you go. What you start out with in our head rarely makes it exactly to the page.

My suggestion? Just write. Nonsense or some senses or poetry or prose. Sentences or words. Keep it coming out and it will come together.

Just keep on keeping on!
