Since there is nothing so well worth having as friends, never lose a chance to make them.
Other quotes by Francesco Guicciardini
Be careful how you do one man a pleasure which must needs occasion equal displeasure in another.

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.
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.
