Charles F. Haanel

The Master Key System is a personal development book by Charles F. Haanel that was originally published as a 24-week correspondence course in 1912, and then in book form in 1916. The ideas it describes and explains come mostly from New Thought philosophy. It was one of the main sources of inspiration for Rhonda Byrne's film and book The Secret .

“You can not entertain weak, harmful, negative thoughts ten hours a day and expect to bring about beautiful, strong and harmonious conditions by ten minutes of strong, positive, creative thought.”
