Watchfulness is the only guard against cunning. Be intent on his intentions. Many succeed in making others do their own affairs, and unless you possess the key to their motives you may at any moment be forced to take their chestnuts out of the fire to the damage of your own fingers.
Baltasar GracianA prudent man will think more important what fate has conceded to him, than what it has denied.
Baltasar GracianMany of the things that bring delight should not be owned. They are more enjoyed if another's, than if yours; the first day they give pleasure to the owner, but in all the rest to the others: what belongs to another rejoices doubly, because it is without the risk of going stale and with the satisfaction of freshness. . . the possession of things not only diminishes their enjoyment, but augments their annoyance, whether shared or not shared.
