From Drucker’s The Effective Executive:
The effective executive makes strength productive. He knows that one cannot build on weakness. To achieve results, one has to use all the available strengths–the strengths of associates, the strengths of the superior, and one’s own strengths. These strengths are the true opportunities. To make strength productive is the unique purpose of organization. It cannot, of course, overcome the weaknesses with which each of us is abundantly endowed. But it can make them irrelevant. Its task is to use the strength of each man as a building block for joint performance.
