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.
My company is going through a major transformation and I found this a really interesting insight to similar major changes at IBM and how one leader dealt with this. It covers the highs and lows/challenges and successes. IBM is clearly a massive complex entity and I was fascinated how such complexity still in the end has to be able to be summarised and netted out to understandable language and concepts. One gets the impression from the book that Gerstner brought this executive ability to take a helicopter view of things. He also was prepared to take tough decisions.
