The 80/20 Principle, like chaos theory, is based around the idea of nonlinearity. A great deal of what happens is unimportant and can be disregarded. Yet there are always a few forces that have an influence way beyond their numbers. These are the forces that must be identified and watched. If they are forces for good, we should multiply them. If they are forces we don’t like, we need to think very carefully about how to neutralize them.
