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.
When you are less believable, start by taking on the role of a student in a student-teacher relationship--with appropriate humility and open-mindedness. While it is not necessarily you who doesn't understand, you must assume this until you have seen the issue through the other's eyes. If the issue still doesn't make sense to you and you think that your teacher just doesn't get it, appeal to other believable people. If you still can't reach an agreement, assume you are wrong. If, on the other hand, you are able to convince a number of believable people of your point of view, then you should make sure your thinking is heard and considered by the person deciding, probably with the help of the other believable parties. Remember that those who are higher in the reporting hierarchy have more people they are trying to sort through on an expected value basis to get the best thinking and more people who want to tell them what they think, so they are time-constrained and have to play the probabilities. If your thinking has been stress-tested by other believable people who support you, it has a greater probability of being heard. Conversely, those higher in the reporting hierarchy must strive to achieve the goal of getting in sync with those lower in the hierarchy about what makes sense. The more people get in sync about what makes sense, the more capable and committed people will be.
