Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.
Marcus AureliusConsider in what condition both in body and soul a man should be when he is overtaken by death; and consider the shortness of life, the boundless abyss of time past and future, the feebleness of all matter.
Marcus AureliusSuch as are thy habitual thoughts, such also will be the character of thy mind; for the soul is dyed by the thoughts.
Marcus Aurelius
