Just finished my second library rental. Jared Diamond offers an insightful look into human history and pre-history and a nice explanation of why things are the way theye are. Guns, Germs and Steel is a great book for history and knowledge and offeres many insights, things one might never consider (like how much faster food spreads East-West versus North-South due to climate, and what that meant for Africa and the Americas versus Asia-Europe), but as far as a personal development book? That it is not.
