Leadership involves engaging others to make a positive difference. Leaders are agents of change who strive for excellence, add value to people's lives, and demonstrate new approaches. They set ambitious expectations, redefine politics, listen to new ideas, and empower others. True leadership is the ability to influence others to work towards a shared vision through voluntary relationships built on trust. Leaders overcome resistance to change by creating urgency, guiding coalitions, communicating a clear vision, and celebrating small wins. They empower teams by providing the right tools and communicating effectively.
