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 AureliusWhen you find an unwillingness to rise early in the morning, endeavor to rouse your faculties, and act up to your kind, and consider that you have to do the business of a man; and that action is both beneficial and the end of your being.
Marcus AureliusHow easy it is to repel and release every impression which is troublesome and immediately to be tranquil.
