If I could travel back in time (and felt justified in changing the past/future) I would give myself The Hacker Ethic ( https://secure.wikimedia.org/wikipedia/en/wiki/The_Hacker_Et... ), Python by Chris Fehily ( http://www.amazon.com/Python-Chris-Fehily/dp/0201748843 ), and Free Software Free Society ( http://shop.fsf.org/product/free-software-free-society/ ). If I could only give one book, I'd choose FSFS

Age doesn't matter. :)
