In the tradition of the New Thought movement, the early "New Age" philosophy popular at the turn of the 20th century, Haanel teaches his readers how the mind is capable of shaping reality. Whether readers want to improve their health or just have better luck, by proper thinking, they can achieve their desired goals. He explains how even destiny is not a force outside our ability to change. Anyone looking for a way to take control of his or her life will be inspired by Haanel's self-help system, first published in 1922. American author and entrepreneur CHARLES F. HAANEL (1866-1949) was a self-made millionaire, member of the American Scientific League and the American Society of Psychical Research, and author of several books including The Master Key System and The New Psychology.
