Marcus Tullius Cicero

Great is the power of habit. It teaches us to bear fatigue and to despise wounds and pain.

Confidence is that feeling by which the mind embarks in great and honorable courses with a sure hope and trust in itself.

Silence is one of the great arts of conversation.

It is not by muscle, speed, or physical dexterity that great things are achieved, but by reflection, force of character, and judgment.

Brevity is a great charm of eloquence.

Let us not listen to those who think we ought to be angry with our enemies, and who believe this to be great and manly. Nothing is so praiseworthy, nothing so clearly shows a great and noble soul, as clemency and readiness to forgive.
