Not every writer is interested in style. If they can write lean, mean plots that move, with interesting characters and a satisfying ending, that’s enough. They’d rather write fast and turn out more work than spend extra time trying to find the “right” words. Isaac Asimov was such a writer. He purposely developed a stripped-down style so he could churn out the books. He was once asked what he would do if he found out he had just six months to live. “Type faster,” he said.
