This book is about 101 successful businesses and how they got started. Although it does not contain details on how to start a business, it contains lots of good ideas and lots of inspiration, two important qualities of a entrepeneur. You will enjoy reading some better known businesses like Terra Chips as well as lesser known ones like Three Dog Bakery who makes gourmet biscuits for dogs. It's amazing a dog biscuit company makes over a million dollars a year, but since this book is about young millionaires, every company profiled in this book makes over this amount.
