I stumbled across The Opposable Mind when I was in a book store looking through business magazines. I had not consistently read HBR but in the latest issue I perused through their "recommended" books... and ran across The Opposable Mind!
Anyways, the book is incredibly underrated and I am somewhat surprised it hasn't "caught on" - it's full of interesting insights into why some successful people are able to attain their success and then even tells the reader how to do so. The basic concept behind the book is that these successful people have the unique ability to hold two very distinct thoughts in their head at the same time and then are able to find a unique solution that most people are not able "to see".
I assure you that the book is a very powerful and interesting read and as further proof I proclaim it one of the best 2 or 3 books I have read in 2007 (out of roughly 80-100 books I read this past year). Indeed, I made my parents order the book so that they would read it as soon as possible.
P.S. As an aside, I mentioned HBR because it is another publication I have stumbled across that I will begin consistently reading - it is full of helpful and interesting business ideas.
