"The Science of Getting Rich" by Wallace D. Wattles is a self-help book promoting a metaphysical approach to wealth acquisition. It posits that a person can attract riches through a combination of intentional thought and action. Wattles argues that there is a universal, formless substance which responds to human thought and that by focusing their mind on a clear vision of wealth, coupled with unwavering faith and gratitude, individuals can create the reality of their desires. The book emphasizes the importance of replacing the competitive mindset with a creative one and encourages readers to act in a manner that contributes to the well-being of others. This method, Wattles claims, will not only attract wealth but also lead to personal fulfillment and overall prosperity.
