If you like Seth Godin's other books, you will like this one. The main riff throughout the book is about the new world of work - one based on intellect and ideas rather than an ability to move stuff from one place to another. While not necessarily a new idea (see Dan Pink's "A Whole New Mind: Why Right-Brainers Will Rule the Future"), it is well presented and compelling. Seth develops his argument for how to succeed in this new world and how to make yourself indispensible. Actually, I think "indispensible" might be a little overstated, I think it would be more correct to say "achieving your full potential to a point where you if you are dispensed with, then someone else will always want you!". Either way, a great message.
It does read a little like a self help book in places. I am not entirely convinced that this was unintentional or necessarily a bad thing. It depends on what you were looking for.
On the downside, some readers might find his "in your face" style a bit evangelical in places, particularly some of us Brits. Undoubtedly, this style has been developed through his blog writing where space is limited to get the point over. However, when the same style is used throughout a book, it can be a bit over powering at times. That said, I read the book cover to cover. Every 2-3 pages I would find a nugget of an idea that would make me carrying on reading. Before long, the book was finished.
Like his other books, I enjoyed reading this one. It helped me understand a little more about the complex world I seem to live in and gave me some further insights into how to get more out of work and life. Recommended.
