This book is well written, concise and comprehensive. It will certainly give you a lift and make you reflect on the mental habits which undermine your effectiveness. It may even lead to long-term changes in your outlook and circumstances. It is therefore worth its price, especially if you're in a rut. But I have a big issue with this and other NLP books (basically this book is pure NLP). The point is that while many of the insights which NLP provides are compelling, changing one's mental habits is not the simple task that this and similar authors would have us believe. It would, to take a parallel example, be unreasonable to expect to hone our body to perfection in seven days, even using the most sophisticated physical training techniques available today. Small matters like genetic characteristics and deeply ingrained self-defeating habits also happen to stand in the way of such aspirations. Similarly, even though the techniques in this book are sound, it is even more unreasonable to expect to reverse years of ingrained conditioning and deep seated habitual thinking and train our minds to become paragons of positive thinking over a short period of time. "Wrong!", the NLP camp protest, "change can happen in an instant". They seem to cite as proof the good feelings that flood through you if you close your eyes and pretend you're a millionaire (or any other state you wish to arrive at). But we can all play make-believe; when you open your eyes and everyday reality returns the euphoria subsides. The real trick is maintaining those good feelings, day in day out, and that can take some serious life-engineering work. You will read numerous example of inspirational people who have lived by these principles and made a success of themselves. Ironically, for a book which claims to change your life in a week, many of the examples are people who took years of dogged determination to achieve success. These stories are uplifting, but they are stories from survivors. What I don't notice are accounts from people who apparently did everything right and still ended up bottom of the heap. Now don't get me wrong, as I've already said the techniques presented here are powerful! I've tried them and I know they can change you. But you're going to have to weave them into your existing mental habits and thinking patterns, many of which have grown strong over the years, and that calls for some hard work over considerable periods of time. Read the book, it will undoubtedly give you an instant buzz, but once the buzz subsides you may find the book languishing on a shelf. Like any other 'change your life' routine, you're going to need to live it - there are no quick fixes and I think it's a little naughty of the commercially minded NLP brigade to pretend there are.
