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.
Unidentified problems are the worst; identified problems without planned solutions are better, but worse for morale; identified problems with a good planned solution are better still; and solved problems are best. It's really important to know which category a problem belongs to. The metrics you use to track the progress of your solution should be so clear and intuitive that they are obvious extensions of the plan.
