The quote sums it all up. This book is worthless, the technical advice is terrible and the mindset advice is also pretty lame. If you want to beat the games and make money playing poker, avoid this book.
"Since poker involves so many borderline decisions, often occurring
one after another, it doesn’t hurt to ask yourself from time
to time (when trying to make up your mind about which way to
go in a hand): “How is my luck running?” Asking yourself this
can be helpful in maximizing your good days and minimizing
your bad days.
As noted, some players ignore this completely. They play each
hand independently, regardless of how their luck is running. You
see these players betting along nonchalantly, playing each hand by
the book, despite being down a lot of money. They have not retreated,
despite the negative flow of events."
