Disaster is virtue’s opportunity

Do not, I beseech you, dread the things which the immortal gods apply to our souls like goads; disaster is virtue’s opportunity. Those whom an excess of prosperity has rendered sluggish may justly be called unfortunate; a dead calm holds them fast, as it were, on a motionless sea. And whatever befalls them comes as a surprise. Cruelty presses hardest on the inexperienced; the neck chafes at the yoke.

~ Seneca
