Effective people do not make a great many decisions. They concentrate on the important ones. They try to think through what is strategic and generic, rather than "solve problems." They try to make the few important decisions on the highest level of conceptual understanding. They try to find out the constants in a situation. They are, therefore, not overly impressed by speed in decision-making. Rather, they consider virtuosity in manipulating a great many variables a symptom of sloppy thinking. They want to know what the decision is all about and what the underlying realities are that it has to satisfy. They want impact rather than technique; they want to be sound rather than clever.
