We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam. The earth is a very small stage in a vast cosmic arena ... It's been said that astronomy is a humbling, and I might add, a character building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known.
Work is not your enemy but your friend. How you work, not what you do, determines the course of your life. You may work grudgingly or you may work gratefully; you may work as a human or you may work as a robot. There is no work so rude that you may not exalt in it; no work so demeaning that you cannot breathe soul into it; no work so dull that you may not enliven it. Never be tempted to diminish your efforts; always do your best. What you plant now, you will harvest later.
