You've already turned in all the grades, scores, numbers, so the Admissions people know what you can do. When you get to essays and interviews they need to know about the person behind those numbers. This is your opportunity to show off who you are, and chances are good that you are not an over-edited, sophisticated treatise on the importance of defending liberty and/or expanding opportunities for all the American People just as our forefathers have done for generations etc ad nausaum. You need to present yourself as the great person your friends, family, co-workers and classmates know and respect. Pick things that'll illuminate who you are, what would make you a good officer, or why you'd be likely to succeed in the program, or share some of the experiences that have formed you. Someone once said that even if your name wasn't at the top of the page the folks that know you should be able to tell who wrote it. The voice you use is a big part of sharing yourself, so don't over-polish.
