One of the original teachers of the power of optimism and self-belief, Christian D. Larson (1874–1954) was a prominent writer and speaker and an early proponent of the power of positive thinking. This seminal book in self-help literature encourages readers to develop their talents and improve their daily lives by assuming a cheerful and supportive attitude. Your Forces and How to Use Them includes "The Optimist Creed," originally developed by Larson under the title "Promise Yourself" and now the cornerstone philosophy of the service club Optimist International. Larson's approach encourages readers to develop their subconscious powers in order to tap into their individual talents and strengths. A classic of the New Thought movement, this volume provides a powerful template for achieving greatness.
