“ There's an old saying that great writing is simple but not easy, and so it is. The search for that one plain but inobvious [SIC] word that will do the work of five, the agony of untangling a complex idea that has become a mess of phrases in the writer's mind, the willingness to keep doing it over and over again until it is right--all of that plus some luck yields prose so clear that it seems a child could have written it. ”
