I've had the book for a good while now, but it's so much psychobabble. It just goes on and on with stories but no actual value (at least for me). A roulette system that really has worked out for me is the Roulette Cash Cow (do a google search) There are many other out there like Martingale and Andrucchi but Roulette Cash Cow is the best.
