It's always easier to kill someone else's darlings than it is to kill your own

"If you've never done it before, you'll find reading your book over after a six-week layoff to be a strange, often exhilarating experience. It's yours, you'll recognize it as yours, even be able to remember what tune was on the stereo when you wrote certain lines, and yet it will also be like reading the work of someone else, a soul-twin, perhaps. This is the way it should be, the reason you waited. It's always easier to kill someone else's darlings than it is to kill your own." (#2 p.213)
