Letting 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 AureliusConsider when thou art much vexed or grieved, that man's life is only a moment, and after a short time we are all laid out dead.
Marcus Aurelius
