Meditations 2.7

Do the things external which fall upon thee distract thee? Give thyself time to learn something new and good, and cease to be whirled around. But then thou must also avoid being carried about the other way; for those too are triflers who have wearied themselves in life by their activity, and yet have no object to which to direct every movement, and, in a word, all their thoughts.

Marcus Aurelius, Meditations 2.7, translated by George Long

Do those things draw thee at all away, which befall thee from without? Make then leisure for thyself for the learning of some good thing more, and cease being carried aside hither and thither. But therewith must thou take heed of the other error. For they too are triflers, who by their activities have worn themselves out in life without even having an aim whereto they can direct every impulse, aye and even every thought.

Marcus Aurelius, Meditations 2.7, translated by C. R. Haines
