I bought this book after having read a review for it, likely in the WSJ. Having more of the mathematical brain, I look for every opportunity to learn about creativity that I can. This book serves that purpose well, primarily through the lens of entrepreneurship, but the framework of the innovation cycle could be used for almost any goal.
With many business books, the ideas are usually quite simple, and the book just provides many case studies about this simple fact. Don't get me wrong - most of these books are successful because their prime audience is people who are pretty good about overcomplicating things. I am a prime member of this group. Creativity books are fairly similar. There's really only two creativity exercises - come up with incredulous solutions without regard to constraints, and figure out which, of those, you could use by re-framing the problem, or adjusting the constraints, and create super restrictive constraints, and solve the problem in that narrow space. Seelig focuses more on the first in this book, but where the value is especially added is in the fact that the book, and its framework, The Innovation Cycle, gives you many tools (and exercises!) to turn this practice into a productive exercise, and move from a thought-exercise activity to fungible goals.
