Meditation 7.6-8
Marcus AureliusMeditationsBook 7.6
6. How many whose praises have been loudly sung are now committed to oblivion: how many who sang their praises are long ago departed.
7. Do not be ashamed to be helped; the task before you is to accomplish what falls to your lot, like a soldier in a storming-party. Suppose you are lame and cannot scale the wall by yourself, yet it can be done with another's help.
8. Let not the future trouble you; for you will come to it, if come you must, bearing with you the same reason which you are using now to meet the present.
