Query: Don't buy this book, don't waste your time reading it.

I really can't figure out why this book was written, other than the author's commission fees. It's long, repetitive, and doesn't have much actionable information. I've taken maybe 5 finance/investment classes, but I'm certainly not a sophisticated investor. Even so, for me the total information value from this book could be boiled down into 3 pages, tops.For the novice, this book would be impenetrable. For the advanced investor, the useful information would fit on a 3x5 card. I have no idea why people rate this book so highly.
