Francesco Guicciardini quotes:

Since there is nothing so well worth having as friends, never lose a chance to make them.

Waste no time with revolutions that do not remove the causes of your complaints but simply change the faces of those in charge.

Few revolutions succeed, and when they do, you often discover they did not gain what you hoped for, and you condemn yourself to perpetual fear, as the parties you defeated may always regain power and work for your ruin.

It is a great matter to be in authority over others; for authority, if it be rightly used, will make you feared beyond your actual resources.

I know no man who feels deeper disgust than I do at the ambition, avarice, and profligacy of the priesthood, as well because every one of these vices is odious in itself, as because each of them separately and all of them together are utterly abhorrent in men making profession of a life dedicated to God.

Ambition is not in itself an evil; nor is he to be condemned whose spirit prompts him to seek fame by worthy and honourable ways.

Even though many people prove to be ungrateful, do not let that stop you from benefiting others-for not only is beneficence in itself a noble and almost divine quality, it may also happen that while you practice it, you will encounter someone so grateful that he will make up for all the others' ingratitude.

Conspiracies, since they cannot be engaged in without the fellowship of others, are for that reason most perilous; for as most men are either fools or knaves, we run excessive risk in making such folk our companions.

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.

One who imitates what is bad always goes beyond his model; while one who imitates what is good always comes up short of it.

If you attempt certain things at the right time, they are easy to accomplish - in fact, they almost get done by themselves. If you undertake them before the time is right, not only will they fail, but they will often become impossible to accomplish even when the time would have been right.

Let no one trust so entirely to natural prudence as to persuade himself that it will suffice to guide him without help from experience.

The return we reap from generous actions is not always evident.

The affairs of this world are so shifting and depend on so many accidents, that it is hard to form any judgment concerning the future; nay, we see from experience that the forecasts even of the wise almost always turn out false.

Like 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.

Affairs that depend on many rarely succeed.

To give vent now and then to his feelings, whether of pleasure or discontent, is a great ease to a man's heart.

We fight to great disadvantage when we fight with those who have nothing to lose.

Pay no heed to those who tell you that they have relinquished place and power of their own accord, and from their love of quiet. For almost always they have been brought to this retirement by their insufficiency and against their will.

Let no one trust so entirely to natural prudence as to persuade himself that it will suffice to guide him without help from experience."

...be more guided by hope than fear.

There is nothing so fleeting as the memory of benefits received.

There is no evil in human affairs that has not some good mingled with it. [It., Non e male alcuno nelle cose umane che non abbia congiunto seco qualche bene.]

As it is our nature to be more moved by hope than fear, the example of one we see abundantly rewarded cheers and encourages us far more than the sight of many who have not been well treated disquiets us.

To 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.

How much luckier than all the rest of mankind are the astrologers who, if they tell one truth among a hundred lies, obtain so much credit that even their lies are believed.

Keep your eye fixed not so much on what they [people] ought in reason to do, as on what they are likely to do based on their disposition and habits.

By numberless examples it will evidently appear that human affairs are as subject to change and fluctuation as the waters of the sea agitated by the winds.

He is less likely to be mistaken who looks forward to a change in the affairs of the world than he who regards them as firm and stable.

He who imitates what is evil always goes beyond the example that is set; on the contrary, he who imitates what is good always falls short.

Experience has always shown, and reason also, that affairs which depend on many seldom succeed.

Ambassadors are the eye and ear of states.
