Principles: Life and Work

What this book is, and who it's for

Ray Dalio, founder of Bridgewater Associates (the world's largest hedge fund), spent decades writing down the principles that produced his best decisions and codifying them into a system anyone in his firm could use to debate, refine, and override individual judgement. The book is two halves: a personal memoir of how Dalio learned to systematize, and the encyclopedia of life-and-work principles themselves. The deeper argument is that 'meritocracy' is only real when you've written down what counts as merit — and that radically transparent disagreement is the engine of any organization that wants to keep improving. Read this if you've noticed your decisions are inconsistent across contexts.
