I love Seth's books, he has an incredible energy and excitement about everything he does. This is an amazing book on so many levels. It contains lots of great marketing ideas, but also many things that will set you thinking laterally. I recommend reading a couple of pieces at a time, as they sink in you will be surprised at all the other stuff that pops into your head.
One author who is better to hear than read.
Have read this classic book a couple of times (albeit ten years ago) before purchasing the audio version. As with other comments the narration is awful and makes Stephen Hawking's speech box sound human! Although it is worth persisting, as with a couple of other reviews would suggest you buy the book for this one. Listening to this has prompted me to re-read and has reminded me how good this book is at providing a systematic approach to innovation and entrepreneurship
