I got "the emperors new mind" by roger penrose when it first came out as I was graduating high school. I found it really good and eye opening. Various books by Tony Buzan ( memory, speed reading, mind mapping ) and six thinking hats (and others) by edward de bono really got me to see our minds are very versatile and, like our bodies, can be pushed in prodded to do lots of things Puzzling through many philosophy books has probably given me some my more dramatic changes in the way I see the world. But not one in specific, each provided little "ah hah!"s All of Calvin and Hobbes The art of war,book of 5 rings, and the prince, all made it clear that strategy and winning are quite different from the sanitized western middle class life I was brought up in.
