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.
Managers will often take the people who work in their organization as a given and try to make the organization work well with them. That's backward. Instead, they should imagine the best organization and then make sure the right people are chosen for it. Jobs should be created based on the work that needs to be done, not what people want to do or which people are available. You can always search outside to find the people who click best for a particular role. First come up with the best workflow design, then sketch it out on an organizational chart, visualize how the parts interact, and specify what qualities are required for each job. Only after all that is done should you choose the people to fill the slots.
