My advice is really this: what we hear the philosophers saying and what we find in their writings should be applied in our pursuit of the happy life. We should hunt out the helpful pieces of teaching and the spirited and noble-minded sayings which are capable of immediate practical application-not far far-fetched or archaic expressions or extravagant metaphors and figures of speech-and learn them so well that words become works.
Seneca the YoungerWhat difference does it make how much there is laid away in a man's safe or in his barns, how many head of stock he grazes or how much capital he puts out at interest, if he is always after what is another's and only counts what he has yet to get, never what he has already. You ask what is the proper limit to a person's wealth? First, having what is essential, and second, having what is enough.
