Query: Must have for people starting their business!

I wish I had this book when I was starting my business. It would have saved me time (and money) in the missteps I had taken. The book is designed as a workbook, so you get to mark your steps as you go along. The layout is beautiful and very well organized.Even after being in business for 5 years, I still found this book extremely useful and motivational. It got me excited about areas of my business that I had lost interest in.I purchased the book after hearing Romanus speak. His enthusiasm is contagious. If you ever get the chance to hear him give one of his presentations, you must go. It is the perfect companion to the book.
