Query: A reference book to be read over and over again

I found this book to be more useful than I had anticipated! I have been researching to start a home business in the near future, and I am real glad that I read this book first. It gave me better insight to pricing my products, it gave me some more tools for advertising on a budget, and many other ideas that either backed me up on my business assumptions or pushed me along with more ideas that I hadn't thought of yet. I have already folded the corners of certain pages that I know I will go back to over and over again as I begin and run my business. This will truly be used as a reference book in my home office!
