"The precepts of the law are these: to live honestly, to injure no one, and to give everyone else his..." — Marcus Tullius Cicero

Never go to excess, but let moderation be your guide.

If you pursue good with labor, the labor passes away but the good remains; if you pursue evil with pleasure, the pleasure passes away and the evil remains.

Never injure a friend, even in jest.

A friend is, as it were, a second self.
