We fight to great disadvantage when we fight with those who have nothing to lose.
Francesco GuicciardiniTo relinquish a present good through apprehension of a future evil is in most instances unwise ... from a fear which may afterwards turn out groundless, you lost the good that lay within your grasp.
Francesco GuicciardiniBe 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 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.
