Principles (book)

Principles: Life & Work is a 2017 book by hedge fund manager Ray Dalio based on principles he had developed while leading Bridgewater Associates. These Principles for Success were also made available as an ultra mini-series adventure by the author. According to The New York Times, staff at Bridgewater were involved in the writing of the book.

The book was on The New York Times Best Seller List and was the top business book of 2017 on Amazon. Despite the book's commercial success and several notable endorsements, few people actually implement the principles.
