One of the greatest personal development books ever written and a foundation of the self-help genre, The Master Key System explains how to harness the power of thought in order to achieve your goals and cultivate your talents and skills. Established as a correspondence course in 1912 and published in book form in 1916, this bestseller forms the original course in New Thought, promising such benefits as advances in mental development and improvements in health and finances. Its timeless teachings employ the law of attraction and creative visualisation, concepts later adapted by Napoleon Hill and the author of The Secret. Twenty-four detailed lessons provide thorough instruction in training your mind to focus on constructive thoughts that lead to positive feelings and favourable outcomes. Each lesson begins with an introduction, followed by instruction and a series of reinforcing questions and answers. A powerful exercise concludes each lesson, demonstrating how to put your new knowledge to practical use. Each lesson brings you closer to mastering your own thoughts and realising your dreams of health, wealth, and love. AUTHOR: American author, philosopher, and businessman Charles Francis Haanel (1866 1940) practiced the principles he preached in The Master Key System. He served as president of the Continental Commerical Company, the Sacrament Valley Improvement Company, and the Mexico Gold & Silver Mining Company.
