A guidebook to personal fulfilment and professional success through "principle-centered leadership" based on timeless principles - showing how goals of excellence and total quality express an innate human need for progress in personal and organizational life. Ineffective people try to manage their time around priorities, says Stephen R. Covey, whereas effective people lead their lives and manage their relationships according to principles - natural laws and governing values that are universally valid. Leadership is the ability to apply these principles to problems, resulting in quality, productivity, profitability and win-win relationships.
