Live each day as if it be your last.
Thou art a little soul bearing about a corpse.
Let it judge that nothing is either bad or good which can happen equally to the bad man and the good. For that which happens equally to him who lives contrary to nature and to him who lives according to nature, is neither according to nature nor contrary to nature.
Do every act of your life as if it were your last.
Let every action aim solely at the common good.
Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.
