Carpentry learned in a library! Wow, no wonder that people make ignorant "just pick yourself up by your bootstraps"-type comments. Complete and utter disconnection from reality.
I don't recall saying there was anything that you could learn in a library that would translate into earning income. Though if I were in a situation where that was my only option, I'd personally pick web programming. That probably has the lowest barrier to entry of anything you could actually learn by just reading a book.
