Every writer needs an editor. It’s not about how technically correct the writing is. It isn’t even about how great the story is.
A writer needs someone to look over the work. How many times have I read the big authors talking about how their spouses read over what they wrote for the day? So many talk about the editors of the old days who worked with writers to improve their works.
I listened to an author speak about a year ago, and one of her classmates from her MFA program read everything she wrote. It seems a natural pairing, an editor and a writer – even if the editor in question has no training.
Why? Well, no matter how many times I look at a manuscript, there always seems to be something I miss. Too close is usually the reason. I think that’s true of many of us, though all writers get to different points on their own before enlisting outside help.
But I think just about every writer I know does enlist outside help, an editor or whomever, at some point.
