Principles are laws applicable to different cultures, times and environments. I used my own and other leaders' experience and lessons and discovered 21 leadership principles. In each chapter of this book, I describes each law as a tool that can help people succeed in business, church, sports, and personal careers. Anyone in any position, any field, and any culture can learn and practice these laws and become a successful leader. Illustrations in real life show how to practice or violate the law to enrich learning.
