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.
If you and others don't raise your perspectives, there's no way you will resolve your disputes. You can surface the areas of disagreement informally or put them on a list to go over. I personally like to do both, though I encourage people to list their disagreements in order of priority so I/we can more easily direct them to the right party at the right time.
The nubbiest questions (the ones that there is the greatest disagreement about) are the most important ones to thrash out, as they often concern differences in people's values or their approaches to important decisions. It's especially important to bring these issues to the surface and examine their premises thoroughly and unemotionally. If you don't, they will fester and cause rot.
