Consider 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 AureliusDon't let your imagination to be crushed by life as a whole. Don't try to pictures everything bad that could possibly happen. Stick with the situation at hand. ...Then remind yourself that past and present have no power over you. Only the present.
Marcus AureliusLook within, for within is the wellspring of virtue, which will not cease flowing, if you cease not from digging.
Marcus AureliusHe who follows reason in all things is both tranquil and active at the same time, and also cheerful and collected.
Marcus AureliusLetting go all else, cling to the following few truths. Remember that man lives only in the present, in this fleeting instant: all the rest of his life is either past and gone, or not yet revealed. This mortal life is a little thing, lived in a little corner of the earth; and little, too, is the longest fame to come - dependent as it is on a succession of fast-perishing little men who have no knowledge even of their own selves, much less of one long dead and gone.
Marcus Aurelius
