He that makes himself famous by his eloquence, justice or arms illustrates his extraction, let it be never so mean; and gives inestimable reputation to his parents.

Seneca the YoungerHe 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.
