The man who backbites an absent friend, nay, who does not stand up for him when another blames him, the man who angles for bursts of laughter and for the repute of a wit, who can invent what he never saw, who cannot keep a secret -- that man is black at heart: mark and avoid him.
Marcus Tullius CiceroDiligence which, as it avails in all things, is also of the utmost moment in pleading causes. Diligence is to be particularly cultivated by us; it is to be constantly exerted; it is capable of effecting almost everything.
Marcus Tullius Cicero
