Epictetus, Golden Sayings 24

If we were as intent upon our business as the old fellows at Rome are upon what interests them, we too might perhaps accomplish something. I know a man older than I am, now Superintendent of the Corn Market at Rome, and I remember when he passed through this place on his way back from exile, what an account he gave me of his former life, declaring that for the future, once home again, his only care should be to pass his remaining years in quiet and tranquility. 

"For how few years have I left!" he cried. 

"That," I said, "you will not do, but the moment the scent of Rome is in your nostrils, you will forget it all. And if you can but gain admission to Court, you will be glad enough to elbow your way in, and thank God for it." 

"Epictetus," he replied, "if ever you find me setting as much as one foot within the Court, think what you will of me."
 
Well, as it was, what did he do? Before even he entered the city, he was met by a dispatch from the Emperor. He took it, and forgot the whole of his resolutions. 

From that moment, he has been piling one thing upon another. I should like to be beside him to remind him of what he said when passing this way, and to add, How much better a prophet I am than you!

What then? Do I say man is not made for an active life? Far from it! . . . But there is a great difference between other men's occupations and ours. . . . A glance at theirs will make it clear to you. 

All day long they do nothing but calculate, contrive, consult how to wring their profit out of foodstuffs, farm plots and the like. . . . 

Whereas, I entreat you to learn what the administration of the World is, and what place a Being endowed with reason holds therein: to consider what you are yourself, and wherein your Good and Evil consists.
