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.
When there were just a few of us, we had meaningful relationships because we knew and liked each other. When we grew to between fifty and a hundred people, we had a community; when we grew beyond that, the sense of community began to slip because we didn't all know each other in the same way. That's when I realized that having groups (departments) of around a hundred (give or take about fifty) that are bound collectively by our common mission was the best way to scale the meaningful relationship. While bigger companies tend to be more impersonal, that is just another challenge that has to be figured out.
