Suggestions? Put it aside for a few days, or longer, do other things, try not to think about it. Then sit down and read it (printouts are best I find, but that's just me) as if you've never seen it before. Start at the beginning. Scribble on the manuscript as you go if you see anything you want to change. And often, when you get to the end you'll be both enthusiastic about it and know what the next few words are. And you do it all one word at a time.
Neil GaimanBe hole, be dust, be dream, be wind/Be night, be dark, be wish, be mind,/Now slip, now slide, now move unseen,/Above, beneath, betwixt, between.
Neil GaimanThere was something about being in the vicinity of Grahame Coats that always made Fat Charlie (a) speak in cliches and (b) begin to daydream about huge black helicopters first opening fire upon, then dropping buckets of flaming napalm onto the offices of the Grahame Coats agency. Fat Charlie would not be in the office in those daydreams. He would be sitting in a chair outside a little cafe on the other side of Aldwych, sipping a frothy coffee and occasionally cheering at an exceptionally well-flung bucket of napalm.
