"The Science of Getting Rich" by Wallace D. Wattles is a self-help guide to achieving wealth that was first published in 1910. The text presents the idea that riches are attainable through a combination of belief, thought, and action. Wattles argues that the universe is permeated with a "Thinking Substance" which can be influenced by human thought. He encourages readers to develop a clear vision of their desired riches, hold this vision with unwavering purpose and faith, and act in ways that align with this vision. The book emphasizes gratitude as a crucial element for connecting with this universal power. Wattles advocates for a creative approach to acquiring wealth, rejecting the competitive mindset that he believes often hinders success.
