Psycho-cybernetics is THE definitive self-help book. I read Maxwell Maltz's original book and benefited immensely. I was a little wary about reading an update. But I'm glad I did. The information is clearly presented, easy to read and there are practical suggestions for putting the advice into practice. If you have to overcome any bad habit, from shyness, lack of confidence, procrastination, chronic lateness, nail-biting, or anything else, you can do it with psycho-cybernetics. Although this version of the book was written 15 years after Maxwell Maltz's death, it is all in the first-person, as though Maltz himself had written it. Gives a new meaning to the term "ghost written"! But if you can live with that, it's a very enlightening book.
