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.
In any conversation, there is a responsibility to express and a responsibility to listen. Misinterpretations and misunderstandings are always going to happen. Often, difficulty in communication is due to people having different ways of thinking (e.g., left-brained thinkers talking to right-brained thinkers). The parties involved should always consider the possibility that one or both of them misunderstood and do a back-and-forth so that they can get in sync. Very simple tricks--like repeating what you're hearing someone say to make sure you're actually getting it--can be invaluable. Start by assuming you're either not communicating or listening well instead of blaming the other party. Learn from your miscommunications so they don't happen again.
