Harness the Power of TR's Charisma Theodore Roosevelt was a leader of uncommon strength who, through the sheer force of his extraordinary will, turned America into a modern world power. Thrown headfirst into the presidency by the assassination of his predecessor, he led with courage, character, and vision in the face of overwhelming challenges, whether busting corporate trusts or building the Panama Canal. Roosevelt has been a hero to millions of Americans for over a century and is a splendid model to help you master today's turbulent marketplace and be a hero and a leader in your own organization.
