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 complaining that the world will not devote itself to making you happy. - George Bernard Shaw -

The longer I'm here the more I experience simple, joyful moments, like when sharing lunch with a family at camp or having a pleasant exchange in town with a street vendor. This joy makes the hard work and exhaustion SO worth it :-).
