Live not as though there were a thousand years ahead of you. Fate is at your elbow; make yourself good while life and power are still yours. – Marcus Aurelius
Every mans life lies within the present; for the past is spent and done with, and the future is uncertain. – Marcus Aurelius
Time is a sort of river of passing events, and strong is its current no sooner is a thing brought to sight than it is swept by and another takes its place, and this too will be swept away. – Marcus Aurelius
Any man of forty who is endowed with moderate intelligence has seen—in the light of the uniformity of nature—the entire past and future. – Marcus Aurelius
