"I was especialy impressed with his explanations of the creative pause, focus, and how to come up with alternatives. His sensitizing techniques are unique and a must read for anyone who wants to optimize their creativity."

"The book would be useful for people who have been in a stable environment, a place where improvements are seen as threats so you couldn't improve most of the things. The negative side was, that there were to many repeats of the same idea through out the chapter and the book." "It is intriguing to hear someone dissect the creative process in a cold, calculating, scientific sort of way, and de Bono does this job quite well without coming off as too fatuous (a common fate in that endeavor it seems). Ultimately though, the creative thinking de Bono discusses is a very specific and fairly limited type, namely problem-solving. It's telling that almost all of the examples & figures he gives are geometric puzzle-solving."
