Remember that the sole life which a man can lose is that which he is living at the moment.
Marcus AureliusNeither in writing nor in reading wilt thou be able to lay down rules for others before thou shalt have first learned to obey rules thyself.
Marcus AureliusEverything is in a state of metamorphosis. Thou thyself art in everlasting change and in corruption to correspond; so is the whole universe.
Marcus AureliusAs surgeons keep their instruments and knives always at hand for cases requiring immediate treatment, so shouldst thou have thy thoughts ready to understand things divine and human, remembering in thy every act, even the smallest, how close is the bond that unites the two.
Marcus Aurelius
