At first glance, this book could easily be overlooked and dismissed as another \\\just buy this book and follow my easy steps to becoming a (genius, millionaire, happier person, psychic, master gardener, whatever)\\\ that would utimately leave you disappointed that you couldn\\\'t do it.Well, this book is not that. It gets right to the point. It\\\'s very well written. It\\\'s fun. It\\\'s practical. And as long as you take your time to mentally practice what you\\\'re learning along the way, you can and should be able to master the techniques in this book. You needn\\\'t have any mathematical expertise going in. Of course, the author doesn\\\'t promise anything special about what you can do with these abilities, although there are some practical applications suggested along the way. All I can say is that it\\\'s fun and gives you something interesting to do with your brain when you\\\'re bored.
