As to the idea that advertising motivates people, remember the Edsel.
Great wisdom not applied to action and behavior is meaningless data.
One does not start with facts. One starts with opinions.
The one to distrust is the person who never makes a mistake, never commits a blunder, never fails in what he tries to do. Either he is a phony, or he stays with the safe, the tried and the trivial.
When a resource is scarce, you increase its yield.
One does not "manage" people. The task is to lead people.
