Editing can be painful. As authors, our words are our children and can be hard to delete, even when we know a scene needs to go. One way to soften the blow is to cut and paste it into an “edits” file arranged by chapter. If you decide to put it back, it’s there.
If you eventually decide it really wasn’t needed, it’s a lot easier to zap that file when the final version goes to press. On the other hand, if you have a real blockbuster on your hands, at some point you may want to work them back in for an “expanded” version or literary “director’s cut” you release later.
