This is a hugely frustrating book. It's the first of De Bono's books I've read; I picked it up in the library, attracted by the somewhat provocative title. I have come across some of his methods and tools (Six Hats, etc) but haven't explored them in any depth.
This book is largely a summary of his main tools and processes, and a manifesto for embracing change in the way we think. So it's certainly given me some idea of the books of his I want to look at. There are some really good and valid points in this book and I can totally see how and why his methods could work.
But. It's repetitive. Was this book designed to be dipped into rather than read straight? I can't think why so many anecdotes and examples had to be repeated. It wasn't effective in making the points. And oh my, it's self-aggrandising. I know that if you're writing a manifesto for the wider use of your tools/theories, you need to point to their successes, but come ON. This book contains literally pages of lists of people who've said nice things about him and awards he's won. He actually seems to say - unless I'm guilty of an uncharitable reading, and I don't think I am - that for 2,400 years, human thought did not advance, until De Bono came along to bring us enlightenment. Dude, really, that's something you should let other people say. To say it about yourself comes across as hubris.
So in summary, I'm interested in some of the ideas, I'll look into them, but if his other books are as self-congratulatory and repetitive as this one, I'll prepare myself for a lot of skipping.
