One of underestimated tasks in nonfiction writing is to impose narrative shape on an unwieldy mass of material.
William ZinsserDon't hedge your prose with little timidities. Good writing is lean and confident. . . . Every little qualifier whittles away some fraction of the reader's trust. Readers want a writer who believes in himself and in what he is saying. Don't diminish that belief. Don't be kind of bold. Be bold.
