Business exists to supply goods and services to customers and economic surplus to society, rather than to supply jobs to workers and managers or even dividends to shareholders.
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 DruckerManagement by objective works - if you know the objectives. Ninety percent of the time you don't.
Peter DruckerWe all have a vast number of areas in which we have no talent or skill and little chance of becoming even mediocre. In those areas a knowledge workers should not take on work, jobs and assignments. It takes far more energy to improve from incompetence to mediocrity than it takes to improve from first-rate performance to excellence.
