When scrolling through "Principles," you'll find short videos peppered throughout the text that give a behind-the-scenes glimpse of life at the secretive Bridgewater headquarters.
On page 171, for example, there's a video of a Bridgewater meeting from January 2011 in which staff discuss the company's successful "Pure Alpha Major Markets" program. Dalio listens while others praise what Bridgewater has accomplished. At the end, he offers his own advice: "We could all be here celebrating, but I think we should be here worrying."
This brings up one of Dalio's principles: "Ring the bell," a term he uses to celebrate when a team has achieved its goals. However, he adds another core principle: "Don't mistake the trappings of success for success itself."
