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 AureliusLook at everything that exists, and observe that it is already in dissolution and in change, and as it were putrefaction or dispersion, or that everything is so constituted by nature as to die.
Marcus AureliusAs for others whose lives are not so ordered, he reminds himself constantly of the characters they exhibit daily and nightly at home and abroad, and of the sort of society they frequent; and the approval of such men, who do not even stand well in their own eyes, has no value for him.
Marcus Aurelius
