you read ALL those already?

damn you're something...

If you haven't I recommend Joseph Heller's "Catch-22". It's my favorite of all time...
I also know lots of people say "Way of the Peaceful Warrior" is a book that can have an impact on how you live life.

My sister also recommended a book called 'Blindness'. unfortunately I'm still stuck in political science readings... (which, if you're ever interested in the first part of Hobbes' "Leviathan" has some very interesting thoughts on humanity and philosophy kinda stuff. I believe that part of the book is titled 'Of Man')
