A Prince should esteem the great, but must not make himself odious to the people. - Niccolò Machiavelli

La quale opera io non ho ornata né ripiena di clausole ampie, o di parole ampollose e magnifiche, o di qualunque altro lenocinio o ornamento estrinseco, con li quali molti sogliono le loro cose descrivere e ornare; perché io ho voluto, o che veruna cosa la onori, o che solamente la varietà della materia e la gravità del subietto la facci grata.

It was the verdict of ancient writers that men afflict themselves in evil and weary themselves in the good, and that the same effects result from both of these passions. For whenever men are not obliged to fight from necessity, they fight from ambition; which is so powerful in human breasts, that it never leaves them no matter to what rank they rise. The reason is that nature has so created men that they are able to desire everything but are not able to attain everything: so that the desire being always greater than the acquisition, there results discontent with the possession and little satisfaction to themselves from it. From this arises the changes in their fortunes; for as men desire, some to have more, some in fear of losing their acquisition, there ensues enmity and war, from which results the ruin of that province and the elevation of another.

A man who is used to acting in one way never changes; he must come to ruin when the times, in changing, no longer are in harmony with his ways.
