The concept in this book is a warm approach to the idea of: only by working in a team will you fulfill your dreams.
The focus of the book is on realizing one's dreams, achieving those goals by working in teams. Teams come in every shape and size - spouses in a marriage, colleagues at work, volunteers together for a good cause...it takes teamwork to make the dream work. There are no lone rangers.
It's a myth that one person can do something great. Strong leaders who changed our country dreamed big and were successful because they were always part of a team.
