Let it be your constant method to look into the design of peoples actions, and see what they would be at, as often as it is practicable and to make this custom the more significant, practice it first upon yourself. – Marcus Aurelius
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. – Marcus Aurelius
