I finally got around to reading Dan Pink's book A Whole New Mind: Why Right-Brainers Will Rule the Future. What makes this book interesting and helpful to me in a way that many "Business" books are not is that Pink doesn't just state a thesis and back this thesis up with facts and anecdotes. Pink also suggests things ways to improve your right brain thinking. He praises other books and suggests you seek those out as well. Hell, he even links to (as best a book can) websites that provide more information on the subject as well. It was very much a book for the web world and was a delight.
On a side note, a person that got a lot of space in A Whole New Mind is Paul Ekman who is a psychologist who is a pioneer in the study of emotions and their relation to facial expressions. Ekman is the basis for the best new TV show of the season on Lie to Me. Give that watch too if so inclined.
