If you are a business owner, a leader in your field, a business coach or a motivational speaker, then you probably already know that a book is not only looked up on as the new business card but is now an expected requirement for the successful entrepreneur.
A book will allow you that extra credibility and prestige that a business card never could. Be honest, what do you do with the majority of business cards that are handed to you? Look at them once perhaps then either store them or throw them away? So is it reasonable to expect that this is what also happens to the cards you hand out? Another great thing about having a book is that people will actually buy it.
