I don't think I could answer that with just one item. It has taught me much more than being a better father, husband, or citizen. It has taught me to see the good in the world. It has taught me to be more compassionate for those that are less fortunate than I. It has taught me what real friendship and brotherly love are. It has taught me to be a better leader and a more thoughtful person. It has taught me to regard less what a person may appear on the outside and consider more what a person is made of on the inside. In my short time as a Mason I have a group of people that I call friends that I have known less time than some of my other friends, but these Masons are closer to me than the others have ever been. I have learned that there others out there that share my views on a great many subjects and disagree with me on several also, but will never judge me less of a person because of it. That is just a few of the things that I can think of right off the top of my head. Given time and introspection I am sure I could come up with many more.
