Leadership is a central influencing factor in the success or failure of any company or organization. What does a leader need to operate efficiently and effectively in times of highly complex economic and political systems? What makes one successful while another fails? What conditions does a company create through specific leadership styles, and how do these influence success? This work uncovers the most significant success factors of leadership through engaging interviews with successful managers and politicians. A practical section with exercises and checklists demonstrates how certain success principles can be integrated into one's own life through self-coaching.
