Principles are ways of successfully dealing with reality to get what you want out of life.
Ray Dalio, one of the world’s most successful investors and entrepreneurs, cites principles as his key to success.
Most people are reluctant to take in information that is inconsistent with what they have already concluded. When I ask why, a common answer is: "I want to make up my own mind." These people seem to think that considering opposing views will somehow threaten their ability to decide what they want to do. Nothing could be further from the truth. Taking in others' perspectives in order to consider them in no way reduces your freedom to think independently and make your own decisions. It will just broaden your perspective as you make them.
