With 10 years of research in leadership and funding from the John D. and Catherine T. MacArthur Foundation to form a not-for-profit think tank called Healthy Companies Institute, Rosen uses his extensive resources to present an absorbing picture of leadership at its best. He draws from case studies of leaders in business, government, and not-for-profit enterprises whose stories reflect what Rosen contends are at the core of a "healthy" organization: vision, trust, integrity, participation, learning, diversity, creativity, and community. He cites the true leader as one with a profound belief that profits follow principles and who, with an astute understanding of human nature, skillfully taps the best in people. We learn that leaders are not born, but are made through key moments in their lives when they learn trust, empathy, and candor. This is an excellent book for entrepreneurs who run their own operations, offering important advice for CEOs who strive to improve their leadership skills. It must be recognized, however, that although the ideal is presented with real leaders profiled, many organizations do not have a culture that values or rewards these skills.
