The job of a professional manager is not to like people. It is not to change people. It is to put their strengths to work.
The organization is, above all, social. It is people.
If there is any one secret of effectiveness, it is concentration. Effective executives do first things first and they do one thing at a time.
Technology is not about tools, it deals with how Man works.
If you have more than five goals, you have none.
Of all the decisions an executive makes, none is as important as the decisions about people, because they determine the performance capacity of the organization.
