"This book provides key research-based principles that will help you be a more effective leader. The first part of the book, "The Concept," gathers some of the best positive psychology research available and reads like a Harvard Business Review article. The second part, "The Story," is a leadership fable about a homeless, former business executive who attempts to climb back into society after a shocking body blow to his life. The research and the story together make a memorable read."--Publisher's description.
