Industry is fortune's right hand, and frugality its left.

John Ray, the 17th-century English naturalist and theologian, made this statement to emphasize the dual qualities necessary for building fortune and long-term success. By saying, “Industry is fortune's right hand, and frugality its left,” Ray highlights that hard work (industry) and careful saving (frugality) must work together, like two hands, to create and preserve wealth.

The quote underscores that industry alone is not enough. A person can work tirelessly and generate significant income, but without frugality—the discipline to manage expenses and save resources—fortune can quickly be squandered. Similarly, frugality without industry will not lead to prosperity, as there must first be something to save. Ray uses the metaphor of the right hand and left hand to show that both traits are equally important and function best in harmony.

The origin of this statement comes from Ray’s collection of proverbs and observations on human behavior, where he often linked virtue, discipline, and success. Living in a time when thrift and work ethic were highly valued, Ray’s words served as practical advice for individuals seeking stability and financial security.

Ultimately, Ray’s message is timeless: to build and maintain fortune, one must be both diligent in generating opportunities and prudent in managing what is earned. Industry and frugality together create the foundation for lasting success.
