He that does good to another does good also to himself, not only in the consequence but in the very act. For the consciousness of well-doing is in itself ample reward.
Seneca the YoungerWhen God has once begun to throw down the prosperous, He overthrows them altogether: such is the end of the mighty.
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.
