This book is about changing our world. It's not about a revolution, but it is revolutionary. It's about serving others--looking at others as people who could use a hand. It's about looking at our hands and realizing that they already contain what others need. This book starts with some assumptions--mainly that people really do want to help one another and make the world better, but they often don't know how to do it. It also assumes that people are looking for meaning and significance in their lives, but they don't know how to find them. They've tried accumulating wealth, tried increasing excitement, tried exercising authority, but those attempts left them empty.
