Leading an organization is different from managing it. Managers want to be efficient. Leaders want to be effective. If people want to develop their leadership skills, the first step is learning to lead. Leadership is a function of knowing oneself, having a vision that is well communicated, building trust among colleagues, and taking effective action to realize one's own leadership potential. This new edition uses wisdom from the world's most successful leaders, helpful self-assessments and dozens of one-day skill-building exercises. It aims to help people become more effective managers and leaders. The workbook format includes more than 30 exercises designed for both personal and group use, offering multiple avenues for development one's leadership skills. Major topics include: leadership for a successful future; managers vs leaders; how to develop an organizational vision and communicate it; the ethics of leadership; and how to harness the power you need to achieve your personal leadership goals.
