Be careful how you do one man a pleasure which must needs occasion equal displeasure in another. For he who is thus slighted will not forget, but will think the offence to himself the greater in that another profits by it; while he who receives the pleasure will either not remember it, or will consider the favour done him less than it really was.
Francesco GuicciardiniTo give vent now and then to his feelings, whether of pleasure or discontent, is a great ease to a man's heart.
Francesco GuicciardiniWe fight to great disadvantage when we fight with those who have nothing to lose.
Francesco GuicciardiniLike other men, I have sought honours and preferment, and often have obtained them beyond my wishes or hopes. Yet never have I found in them that content which I had figured beforehand in my mind. A strong reason, if we well consider it, why we should disencumber ourselves of vain desires.
