I am forced to give the book a low rating because it's not what the public is led to believe it is. It's not really a book on entrepreneurial success so much as it is a fast overview of a multitude of topics stretching from economic history to the evolution of the venture capital industry to human resources management, and finally, to actual startup advice.
I might add that all of these topics are delivered in short snack-sized pieces of, at best, a couple of paragraphs. Which means that just as you start to find the topic interesting and relevant, it's over and the author moves on to something completely different. This leaves the reader frustrated from wanting more depth.
If you are looking for startup advice (the promised "roadmap to success"), you will not find it here.
One final point on the author's outline for a business plan. While it looks pretty comprehensive at first blush, following it would result in a document close to 100 pages in length. If the author had any real world experience in entrepreneurship, he would understand that busy investors are extremely reluctant to read anything over 20 or at most 30 pages in length and view longer plans as a sign of poor writing and editing skills.
If you need a good practical startup manual, this is not it, instead check out Rob Adam's A Good Swift Kick in the A**.
