Bear in mind that every man lives only this present time,

 Bear in mind that every man lives only this present time, which is an indivisible point, and that all the rest of his life is either past or it is uncertain. Short then is the time which every man lives, and small the nook of the earth where he lives; and short too the longest posthumous fame, and even this only continued by a succession of poor human beings, who will very soon die, and who know not even themselves, much less him who died long ago. Marcus Aurelius.  Meditations.  Book 3.
