"The Science of Getting Rich" by W. D. Wattles is a book published in 1910. Wattles presents what he calls the "Certain Way of Thinking," a mental technique rooted in New Thought philosophy that promises to unlock financial prosperity through positive mindset and self-affirmation rather than competition. The work applies mental healing strategies to wealth creation, offering seventeen chapters on overcoming mental barriers. Though widely regarded as pseudoscientific, it inspired later success literature and Rhonda Byrne's "The Secret," remaining influential in personal development circles.
