Think of what you have rather than of what you lack. Of the things you have, select the best and then reflect how eagerly you would have sought them if you did not have them.
Marcus AureliusLet 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.
Marcus Aurelius
