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.
I have seen some people who have repeatedly failed at something hold strongly to their opinions of how it should be done, even when their opinions are at odds with those who have repeatedly done it successfully. That is dumb and arrogant. They should instead ask questions and seek believability-weighted votes to help them get out of their intransigence.
