The title says it all. Its good, but I approached the book in the wrong way (I read it like a novel), and thats not how its supposed to be read, since not all of the chapters were relevant to me. A tip: Get a highlighter and as you go, highlight the parts which you think you could improve your mind with. That way, youll be more focused on what you need to do. You may find it a little bit boring sometimes (As I did, hence why it took 5 months to finish reading) because youre very likely to have a beautiful mind already =) Some of the things De Bono mentions were quite obvious, so if you find it boring, just skip that chapter and move on to something more relevant to you.
