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.
Everyone has weaknesses and they are generally revealed in the patterns of mistakes they make. The fastest path to success starts with knowing what your weaknesses are and staring hard at them. Start by writing down your mistakes and connecting the dots between them. Then write down your "one big challenge," the weakness that stands the most in the way of your getting what you want. Everyone has at least one big challenge. You may in fact have several, but don't go beyond your "big three." The first step to tackling these impediments is getting them out into the open.
