Query: A Fascinating Read !

This has been one of the few books I have read lately that really makes me think about what makes me tick but also the larger issues that guide us all -- not only in how we work but what we value in life. The chapters on the four drives are some of the most interesting I have ever read -- though it feels like this topic is just really beginning to be explored. This book will stay on my shelf to be picked up and reread. Very thoughtful.
