It's like reading a book on how to win at poker. Only way that works is if the dude has stopped playing poker, otherwise do you really think he is going to give away his edge? And if he's stopped playing poker, then ask why? Has enough money? Then why is he asking you to pay for the information?
Be wary of all financial advice. Cracks me up to see all these financial guys going on TV and telling folks what to do. You know they are tailoring this information to fit what they want you to do, because they want you to make choices that help their portfolio. They aren't interested in you getting rich.
