That crazy Australian dentist, Paddi Lund, has a wonderful book called "building The Happiness-Centered Business".
Solutions Press - Introducing Dr Paddi Lund Business, Happiness & Money, Never Mixed ... Until Now!
I have read the book several times but I don't have any of his more expensive materials.
While my bottom line is a net profit goal.. the top line is to enjoy owning a business that is enjoyable and challenging. Otherwise why bother?
