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.
There are all kinds of different people in the world, many of whom value different kinds of things. If you find you can't get in sync with someone on shared values, you should consider whether that person is worth keeping in your life. A lack of common values will lead to a lot of pain and other harmful consequences and may ultimately drive you apart. It might be better to head all that off as soon as you see it coming.
