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

Something Truly Remarkable

"Perhaps the most startling truth about human nature is that anyone can do something truly remarkable in life if he or she has something truly remarkable to do. Once you decide what you really want, the rest falls into place. You awaken each morning with a reason to get out of bed. Your days are filled with meaning because you fill them with meaningful work. You are able to take advantage of your talents, your time, and your opportunities because you have a purpose."
