Query: Don't waste your time or money

I bought this book based on the title, description of it's content, and a few abriged excerpts. And after reading half of it, I realized that I was learning nothing, and was wasting time that I could use reading something useful about investing. This book is not about investing, nor trading. And it's definitely not about the practical speculation of financial markets. It seems much more like a Wall Street Journal, Barron's, or CNBC feature that got out of hand, or a graduate students thesis paper.Take your trading and investment lessons from those who make a lot of money from professional trading and investing, not from professional writers who make a living writing.
