Our life is what our thoughts make it. Do every act of your life as if it were your last. In a word, your life is short. You must make the most of the present with the aid of reason and justice. Since it is possible that you may be quitting life this very moment, govern every act and thought accordingly.
Marcus AureliusBe not as one that hath ten thousand years to live; death is nigh at hand: while thou livest, while thou hast time, be good.
Marcus AureliusPerfection of character is this: to live each day as if it were your last, without frenzy, without apathy, without pretence.
Marcus Aurelius
