It may be that the most important element of effective communication is repetition, even while it is the most unappreciated. We tend to arrogantly claim that we only need to hear things once. When a parent repeats an instruction, children roll their eyes. When a boss repeats a familiar command, employees complain that it is superfluous. When a teacher reviews material already taught, students complain they already know the material. We tend to believe we can receive information or commands and never again need a reminder or renewed encouragement.

We pass them by every day on the roads that we travel without much thought or recognition. Little green signs, with white numbers marking the distance in miles from a starting point, blend into the scenery beside the road. These mile marker signs are part of a very long history that stretches back to the first constructed roads. There still stands today beside the roads that the Romans constructed stones engraved numbers indicating the distance from Rome. These stones are called milestones. With this long history, the word "milestone" has found a place in our lexicon not only referring to an object that indicates the distance from a specific point but also to a moment in time that has significance or distinction.

This past weekend I traveled to Columbus, GA, to celebrate a milestone with my dad, who is also named Ben Smith. On Friday, September 1, 1978, my dad started running. From the start, he recorded his running miles and eventually would add them to an Excel file to keep track of his total distance. I was a little boy when he started running, so I do not remember a time when he was not a runner. I do remember that over the years, I would hear him mention different goals that he was striving for. In the early 1980’s he was training to qualify and then run the Boston Marathon. Years later, as his total distance of running approached the distance in miles equal to the distance around the Earth at the equator (24,901 miles), he regularly made announcements as to how close he was getting. When he reached this milestone, he was running with some of his longtime running partners. They stopped and used a disposable camera to capture the moment then continued their run.
