I just finished `The Carrey Formula` by Barbara Carey, it is excelent. It is for people who have product ideas/inventions and want to make a business out of them. Step by step stuff and some inspiration.
I really enjoyed this book. I agree both practical and inspirational, complete with a monumental failure or two.
I am currently reading "Think and Grow Rich" By Napolean Hill - It`s a pretty good book so far, seems like `The Secret` borrowed a lot of it`s ideas from this book.
Rich Dad Poor Dad is another good one.
Neither of these really have the step by step way to start a business that it seems you are looking for, but they both definately make you start thinking in different ways
