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.
As Carl Jung put it, "Man needs difficulties. They are necessary for health." Yet most people instinctually avoid pain. This is true whether we are talking about building the body (e.g., weight lifting) or the mind (e.g., frustration, mental struggle, embarrassment, shame)--and especially true when people confront the harsh reality of their own imperfections.
