Some food for thought has no expiry date:

"One can live joyously - one must! in the midst of a world peopled with sorrowing, suffering creatures. What other world is there in which to enjoy life? I know this, that I will no longer perform for the sake of performing, nor take action for the sake of being active. Nor can I acknowledge as necessitous or inevitable what goes on in the name of law and order, peace and prosperity, freedom and security."

(Henry Miller)
