Thanks! This book also had quite an effect of me when I read it. It makes one think about how often we waste this short life and how much can be done if we just had more discipline and focus on the right things. I'm sure it would similarly effect me if I were to reread it.
And don't forget one of his more interesting contributions... he pushed for the creation of libraries! I don't remember if it was through private book lending clubs or if he was the first to suggest public libraries, or what, but I do seem to remember something along those lines.
