In his final lesson in Law of Success, Napolean Hill discusses “the Golden Rule”, and how he believes it to be the driving force in gaining success. “The Golden Rule” is defined as “the guiding star that will enable you to profitably and constructively use the knowledge assembled in the previous lessons".
To put it simply, following this law is the only way to apply the power that the preceding lessons provide. The universal definition of “The Golden Rule” is to do unto others as you would wish them to do unto you if your positions were reversed. This must be taken very seriously, as Hill stresses the fact that all of your actions and thoughts will come back to you, for better or worse. It is not enough to merely believe in the philosophy of the Golden Rule, but rather one must apply it.
The primary key to this lesson is that the Golden Rule, when understood and applied, makes dishonesty, selfishness, greed, envy, hatred and malice impossible to maintain. One must be blatantly honest, and realize you are only punishing yourself by every wrong you commit, and rewarding yourself by every act of constructive conduct.
