a healthy fear of being wrong and figured out an approach to decision making that would maximize my odds of being right. - Ray Dalio

Making a handful of good uncorrelated bets that are balanced and leveraged well is the surest way of having a lot of upside without being exposed to unacceptable downside.

My approach was to hire, train, test, and then fire or promote quickly, so that we could rapidly identify the excellent hires and get rid of the ordinary ones, repeating the process again and again until the percentage of those who were truly great was high enough to meet our needs.

Never say anything about someone that you wouldn’t say to them directly and don’t try people without accusing them to their faces.
