This book is a work book that you have to work through. It allows you to focus on who you want to market your product or service to, how to reach them, and what to do once your target market are contacting you through your various marketing schemes. It is comprehensive, and has allowed me to really understand business and marketing. I think that E myth, public speaking for professionals, and books for marketing on the internet also support the information in this book well. This book will open your eyes and give you some idea of what it takes to succeed in business, but remember that this book is just a starting point.
