I once was leaving my office late after a challenging day. Just as I was locking the door, a student whom I barely knew asked if he could speak with me for a few minutes. My initial thought was to ask him to come back tomorrow. I’d already worked later than usual and I was tired, but I noticed something in his eyes, so I unlocked my door and invited him in.

My first college football coach had three rules. 1: Walk on the sidewalk. He said if we were supposed to walk on the grass, God would not have created concrete for us to walk on. 2: Don’t wear your hat inside. Wearing a hat inside will make you lose your hair. 3: Do whatever Coach tells you to do. Rule #3 pretty much covered everything else in our lives.

Like every set of rules, there were both good and bad consequences depending on whether or not we followed them. One positive consequence was that a young man could end up with an NFL contract after playing football for Coach. One negative consequence was that a young man could find his scholarship taken away the third time he broke the team rules—any of them.
