The same can be said of a novel. Too much polishing and refining can erase the early energy and excitement of the first draft. It’s important to reread that first telling of your story before you send out your manuscript. Although the first draft is rough, in terms of vocabulary and structure, it may have an electric quality that you want to maintain. Make sure the original spark is still there and that the early energy hasn’t been diluted.
If it has – put it back again.
