Everything is only for a day, both that which remembers and that which is remembered. Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are and to make new things like them. For everything that exists is in a manner the seed of that which will be.
Marcus AureliusYour mind will take on the character of your most frequent thoughts: souls are dyed by thoughts.
Marcus AureliusThe longest-lived and the shortest-lived man, when they come to die, lose one and the same thing.
Marcus AureliusThe things you think about determine the quality of your mind. Your soul takes on the color of your thoughts.
Marcus Aurelius
