It may seem very strange, but except for the (half) colourful cover, de Bono is not very creative or innovative with this book.
The major problem is that some authors do think everyone has the same representational system and for those who are visual - as I am - all the pages in this book looks like a novell, not a technical book, especially on creativity. It is addressed exclusively to the left side of the brain! What about the other half? (the creative one!).
OK, lets assume that's a problem that no one else has, except me... I read the book, and then what? Must I remember all the exercices or do nothing else but practice them as practice turns into perfection?
Sorry de Bono, I gave 3 stars just because it's a book from you...
My recommendation is for the readers to look deeper into Amazon's vast offer and you'll find lots of most cativating and interesting books on this subject of creativity.
