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.
Work is either 1) a job you do to earn the money to pay for the life you want to have or 2) what you do to achieve your mission, or some mix of the two. I urge you to make it as much 2) as possible, recognizing the value of 1). If you do that, most everything will go better than if you don’t.
