Here are the last four of Napoleon Hill’s Code of Ethics. Isn’t it cool how principles stressed decades ago still prove to be the key fundamentals for success today?
IX. When my mind is not occupied with thoughts that tend toward the attainment of my definite chief aim in life, I will voluntarily keep it filled with thoughts of courage, and self-confidence, and good-will towards others, and faith, and kindness, and loyalty, and love for truth, and justice, for I believe these to be the seed from which the world reaps its harvest of progressive growth.
X. I understand that a mere passive belief in the soundness of the Golden Rule philosophy is of no value whatsoever, either to myself or to others; therefore, I will actively put into operation this universal rule for good in all my transaction with others.
XI. I understand the law through the operation of which my own character is developed from my own acts and thoughts: therefore, I will guard with care all that goes into its development.
XII. Realizing that enduring happiness comes only through helping others find it; that no act of kindness is without its reward, even though it may never be directly repaid, I will do my best to assist others when and where the opportunity appears.
So now you have all twelve. Now I challenge you to live and work in this way!
