While visiting the campus of Purdue University on a frigid winter day, I came upon two young men chipping away thick ice on the sidewalk next to a fraternity house. Thinking they must be underclassmen who had been assigned the tough job by older fraternity brothers, I said, “They didn’t tell you about this when you joined, did they?” One looked up with a smile and said, “Well, we’re both upperclassmen. I’m the fraternity vice-president and my friend here is the president.” I thanked them for their hard work and went on my way having been reminded that serving others is the mark of a true leader.
