I'm more than half-way through and maybe it's just my left-brain (even though tests show I'm sort of more right-brained?) getting in the way but I'm rather frustrated about how every chapter seems to say no, it's not just what we said in the previous chapter, it's this! Like relaxation is essential unless you're productive when you're under stress. Then stress! ADHD sufferers excel, except here, take some amphetamines and focus intently, except, hey, you lost all that right-brained disparate input. Perhaps it's a sign of just how complicated the subject matter is but, it's rather frustrating picking through this book and saying, "but wait a minute, back here you said this, and now your saying not-this?"

In the end, I've enjoyed it, but I feel as if it is living testimony to how little we understand about imagination, innovation's spark in the mind, and how one person's creatively stifling situation is another's crucible of innovation and insight.
