Kill Your Darlings Go read.
It’s hard. Sacrificing the beautiful words, the clever phrases, the heart-breaking scenes. But it has to be done. The novel will be better for it, and only you will know how much it hurt to chop out everything that didn’t serve the story.
There isn’t much you can do about the words and phrases unless you’re the type who keeps a file of discards — just in case. But the scenes? Take them out, give them their own fresh white page, and let them mellow and fade in your memory. Then go back. Maybe you’ll see the core of a short story.
