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.
I constantly see people form wrong opinions and make bad decisions, even though they've made the same kinds of mistakes before--and even though they know that doing so is illogical and harmful. I used to think that they would avoid these pitfalls when they became aware of their blind spots, but typically that's not the case. Only very rarely do I hear someone recuse himself from offering an opinion because they aren't capable of forming a good one in a particular area. Don't bet on people to save themselves; proactively guardrail them or, better yet, put them in roles in which it's impossible for them to make the types of decisions they shouldn't make.
