After I read this quote I remembered the times I've struggled to get it right on a brief. Ultimately I would come out the other side, with the satisfaction of having achieved a measure of clarity of an idea on paper. Not sure how long that feeling lasted (!) but my point is that I think it is difficult to be a good planner if you are a poor writer.
That said, here is the quote:
“Writing is finally about one thing: going into a room alone and doing it. Putting words on paper that have never been there in quite that way before. And although you are physically by yourself, the haunting Demon never leaves you, that Demon being the knowledge of your own terrible limitations, your hopeless inadequacy, the impossibility of ever getting it right. No matter how diamond-bright your ideas are dancing in your brain, on paper they are earthbound.”
- William Goldman, author, screenwriter, on the uncertainties of show business
