Principles: Life and Work

Dalio founded Bridgewater Associates out of his apartment in 1975 and built it into the largest hedge fund in the world, and this is his attempt to write down the decision rules he thinks did it. The first part is autobiography, organised around the bet that nearly destroyed the firm in 1982 — he had predicted a depression, said so publicly, was wrong, and lost almost everything. The lesson he draws structures the rest: that being right matters less than knowing how you could be wrong, and that an organisation should therefore be engineered to surface disagreement rather than suppress it. The life and work principles that follow are the machinery for that — radical transparency, an “idea meritocracy” where opinions are weighted by track record, and a practice of treating pain plus reflection as the only reliable source of progress.

Why it’s on the list: The rest of Li Lu’s value-investing section is about how to appraise a business. Dalio is the entry about how to run the organisation doing the appraising — the systems that keep a firm’s judgement honest, which for a long-horizon investor is the same problem one level up.

Where I saw it: On Li Lu’s Recommended Book List, the 137-entry Himalaya Capital bibliography, in the section on Value Investing, Finance, and Capitalism — the one section Kyle’s two saved X posts did photograph. The full list came from the source PDF.
