This document summarizes the key lessons from a presentation on "The 21 Irrefutable Laws of Leadership" by Dr. John L. Mason given at the 42nd Annual SAEOPP Conference in New Orleans. The presentation reviewed six of the leadership laws including the Law of Influence, the Law of Process, the Law of Navigation, the Law of E.F. Hutton, and the Law of Solid Ground. Interactive exercises were used to illustrate each law and help attendees understand how to apply the laws to become better leaders.
