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 YoungerFinally, everybody agrees that no one pursuit can be successfully followed by a man who is preoccupied with many things-eloquence cannot, nor the liberal studies-since the mind, when distracted, takes in nothing very deeply, but rejects everything that is, as it were, crammed into it. There is nothing the busy man is less busied with than living: there is nothing that is harder to learn.
