If you want to master the art of the sentence, you must first accept a somewhat unpleasant truth--something a lot of writers would rather deny: The Reader is king. You are his servant. You serve the Reader information. You serve the Reader entertainment. You serve the Reader details of your company's recent merger or details of your experiences in drug rehab. In each case, as a writer you're working for the man (or the woman). Only by knowing your place can you do your job well.
