I am coming to understand and appreciate, the best editors aren’t just checking for spelling mistakes and grammatical errors, they’re reading your mind. They’re knowing what that turn of phrase is that you’re trying to remember, but can’t. They’re spotting the plot-holes, the weak characters, the sloppy prose, the omissions. They’re understanding what you mean to say even when you yourself aren’t exactly clear what that is. And they’re evaluating whether you’re achieving your aim in every sentence and paragraph and chapter, even when you yourself are having difficulties articulating precisely what that should be.
