You’ll learn to become a full-time influencer, focus on a handful of key behaviors that drive exponential results, and leverage six sources of influence (personal, social, and systemic motivation and ability) to remove barriers and fuel action. Whether you’re a manager, educator, parent, or community leader, this book gives you actionable strategies to break through resistance, align others with shared goals, and turn ambitious visions into reality.
