Query: Purely academic; no practicum

I concur completely with the review posted by Karl from England. This book is a purely theoretical book that presents the information, but is void and useless without some sort of practicum. The title claims, "how to...", yet contains no information of that kind. Lots of glittering generalities, yes. Specific suggestions, not a one. It reads like a large collection of short stories of people who have triumphed over their past shortcomings. I was expecting a detailed, step-by-step how-to book. The author may be well-informed and skilled in influencing, but his book does not fulfill its promise. I am very disappointed.
