The book subject are methods to increase personal creativity and spur inventions. Being a skeptic I consider this book the typical product of an American culture who believes in the miracles of positive attitude to change reality (to make the grass grow faster than otherwise, as with tongue in cheek a Frenchman put it), in the power of religious prayers to positively solve problems in this world, in the widespread belief that by baptizing situations with a misleading name it would change reality (like by naming a town close to the Arctic Circle “Paradise City” its weather will change and palms with grow under a scorching sun), and the list of gullible beliefs goes on.
In short, to me, the advertised methods for becoming creative look like platitudes and smoke and mirrors solutions covered by a skillful verbiage; after all, individual talents like real creativity, intelligence or geniality are innate, and impossible to acquire in a crash course.
The author, a marketing consultant, fills the book with examples of product introduction and marketing techniques, labeling them as creativity, which on one hand they are not, and on the other hand they are of no interest to the general readers who are not employed in marketing, but work in many different professions.
In engineering, a field I know well, the road to useful minor innovations (as opposed to inventions, which belong only to geniuses like Freyssinet, the inventor of prestressed concrete or Newton, the discoverer of gravity law) and to professional creativity in solving problems nobody around could solve pass through a long carrier (at least ten years according to a famous book I heard of, better twenty or thirty in my opinion), a broad knowledge of foreign codes and ways of doing things in different parts of the world, a passion which translate in sacrificing numerous hours of free time and research of specialized papers and of course a decent IQ. I am sure the same is valid in music, medicine, academic life and most others professions. Paraphrasing Euclid, there is no royal way to creativity except long and hard work. I did not learn anything useful from this book and consider its reading a waste of time for me, but I recognize that this is only a personal opinion.
The book is a pleasant reading despite its lack of convincing content and some may enjoy reading it.
