One can write instinctually and get published if it goes well. Later on, if necessary, one can smoothen out the rough patches of one’s instinctual style and become a better writer. Therefore one has had experience on one’s side, publishing credits, and an eye to improve for that next piece and the one after that and the one after that…until the writer reaches a plateau of something satisfactory to his or her eye. Then there are more things he may need to improve on. Later he starts thinking, I can relax. He’s done his best and whatever the publisher thinks, he’s always done his best.
