How to Live and Work Based on 'Principles'

(Bloomberg View) -- Investors need to create a set of principles to guide their work and personal decision-making. So says this week's Masters in Business guest Ray Dalio, head of hedge fund Bridgewater Associates LP, which manages more than $160 billion. Dalio details the specifics in his book, "Principles: Life and Work," a New York Times bestseller.

Dalio developed these principles by tracking his trading results: before any new position was taken, he wrote down exactly what criteria guided his decision; later, a thorough postmortem was performed. That process eventually became a rule that could be validated across different eras and regions. A full decision-making system which “operated like a GPS” to assist the investment of Bridgewater’s capital was the result.

The system’s success led Dalio to develop similar processes for managing Bridgewater, its procedures and employees. The firm’s culture became an idea meritocracy. The goal: raising the probability of being right, regardless of any ideas’ authorship. 

Some of Dalio’s favorite books are here.
