Principles: Life and Work
Ray Dalio, founder of Bridgewater Associates, lays out the principles he developed over four decades of building and running the firm, along with the personal history that shaped them. The book is split into a memoir of his career, a set of life principles, and a set of work principles focused on radical transparency and idea meritocracy. Dalio walks through mistakes, including the near collapse of his firm in the early years, and treats each one as an occasion to extract a rule. He explains Bridgewater's practices around recording meetings, rating people in real time, and forcing disagreements into the open. The book has become a touchstone for founders and investors, though its culture has also attracted debate.
