True joy...

This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being thoroughly worn out before you are thrown on the scrap heap; the being a force of Nature instead of a feverish selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy.
George Bernard Shaw


And no, joy is not pain, Miss Abelbeck. I recant my previous statement. :)
