Being an Agent

from Happiness & Philosophy: Being an Agent:

"'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. And also the only real tragedy in life is the being used by personally minded men for purposes which you recognize to be base. All the rest is at worst mere misfortune or mortality.'"
