Do not fear death, but welcome it, since it too comes from nature. For just as we are young and grow old, and flourish and reach maturity, have teeth and a beard and grey hairs, conceive, become pregnant, and bring forth new life, and all the other natural processes that follow the seasons of our existence, so also do we have death. A thoughtful person will never take death lightly, impatiently, or scornfully, but will wait for it as one of life's natural processes.
Marcus AureliusRemember how often you have postponed minding your interest, and let slip those opportunities the gods have given you. It is now high time to consider what sort of world you are part of, and from what kind of governor of it you are descended; that you have a set period assigned you to act in, and unless you improve it to brighten and compose your thoughts, it will quickly run off with you, and be lost beyond recovery.
Marcus AureliusAn angry look on the face is wholly against nature. If it be assumed frequently, beauty begins to perish, and in the end is quenched beyond rekindling.
Marcus Aurelius
