I highly recommend Ishmael.

I just got done reading this insightful work of fiction known as "Ishmael", written by Daniel Quinn. In it, the writer replies to a magazine ad for a pupil, with "urgent need to save the world" listed as a requirement. He goes to the place listed and finds that he's being lectured on the history of the "takers" and "leavers" from an articulate gorilla. But the lesson the gorilla teaches him rings true in society as we know it today. It's truly something that is worth thinking about. I strongly urge you to look this book up, it's a must-read for anyone serious about changing the world and making it a better place to live.
