I found this and thought it was motivating:
My experience is that there is no such thing as “A Marine”. Oh, there are individual Marines, but not singular Marines. There is one Marine, there is Marine by himself, but no such thing as “a Marine”. The very word is plural in its spirit. Every Marine who ever earned the title United States Marine is permanently connected to every other Marine that ever wore the Eagle, Globe and Anchor. From the first recruit, to the last we are bound together by the Corps’ Values: honor, courage, commitment. By our shared history. We are connected by blood. They are the bedrock of the character of Marines. Like links in a chain stretching from first to last, always faithful to each other, to our mission, to our country.
