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 make bad decisions because they are so certain that they're right that they don't allow themselves to see the better alternatives that exist. Radically open-minded people know that coming up with the right questions and asking other smart people what they think is as important as having all the answers. They understand that you can't make a great decision without swimming for a while in a state of "not knowing." That is because what exists within the area of "not knowing" is so much greater and more exciting than anything any one of us knows.
