This document discusses the importance and power of persistence. It argues that persistence is developed through four steps: having a definite purpose with burning desire, having a definite plan of continuous action, closing one's mind to negative influences, and forming friendly alliances with encouraging people. It provides examples of how persistence allowed people like Henry Ford and Thomas Edison to achieve great successes and how persistence helped King Edward VIII and Wallis Simpson find love despite facing immense criticism. The document advocates studying the examples of persistent people to help one find life's greatest rewards.
