Principles are concepts that can be applied over and over again in similar circumstances as distinct from narrow answers to specific questions. Every game has principles that successful players master to achieve winning results. So does life. Principles are ways of successfully dealing with the laws of nature or the laws of life. Those who understand more of them and understand them well know how to interact with the world more effectively than those who know fewer of them or know them less well.

Be an effective imperfectionist. Solutions that broadly work well (e.g., how people should contact each other in the event of crises) are generally better than highly specialized solutions (e.g., how each person should contact each other in the event of every conceivable crisis).
Ray DalioOver time, it also became important for me to share my management principles with the people I worked with because we had to agree on how we should be with each other - and that way is unique. Because the logic behind being radically honest and radically transparent with each other wasn't clear, it had to be spelled out in these principles.
