Query: What a disappointment!

I loved Zyman's earlier book, so I expected more of the same. But not until page 82 did I encounter a single fresh idea or interesting example. This reads like the outline for a book that was slapped together. It's not that the advice is wrong. It's good advice, but there is no depth and no originality to it, and very little worthwhile content.
