The most critical case in a corporation, especially a big one, is when everything goes well, when you have accomplished your objectives. When the temptation is to work twice as hard instead of saying, "We have accomplished our objectives, we have to think again."
Peter DruckerDon't take on things you don't believe in and that you yourself are not good at. Learn to say no. Effective leaders match the objective needs of their company with the subjective competencies. As a result, they get an enormous amount of things done fast.
Peter DruckerI no longer think that learning how to manage people, especially subordinates, is the most important for executives to learn. I am teaching above all else, how to manage oneself.
Peter Drucker
