Leadership is learnable--it begins with leading oneself. Leadership is inspirational--it inspires in others the sustainable values that guide their pursuit of success and significance in life. Inspiration, transparency, trust, reputation, purpose, and commitment have become the operating currency of leadership in a morally interdependent world. The most powerful form of human influence is inspiration. Inspiring and nurturing the world's future leaders in a secondary-school setting merits being an educator's highest priority and most lasting legacy. Leadership is no longer just for formal leaders. The nation's secondary schools must find a way to cascade leadership across the campus to create millions of new dispersed leaders.
