From ToastMaster Clarence:
Below is a Youtube link to a speech from Lou Holtz regarding self-improvement and staying in the game. Should you not know, Lou Holtz is, arguably, the greatest college football coach of all time. Please note his use of humor and the audience behind him. As he starts to lose them with facts and information, his humor brings them back to attention.
