The only reason that this book got two stars is because it has a bit of extra info that is not worth the money this book asks for - Firstly its a really small book which can be finished under an hour , secondly it has no solid info, it seems like the articles on your sunday paper have been put together and made into a book, not worth it.
This book is clear with great information. It has possibly saved me from making some big mistakes. I love his Blueprint and Checklist they are so helpful. It really is a handbook that you should take with you.
