The Romans never allowed a trouble spot to remain simply to avoid going to war over it, because they knew that wars don't just go away, they are only postponed to someone else's advantage. Therefore, they made war with Philip and Antiochus in Greece, in order not to have to fight them in Italy... They never went by that saying which you constantly hear from the wiseacres of our day, that time heals all things. They trusted rather their own character and prudence- knowing perfectly well that time contains the seeds of all things, good as well as bad.

Sometimes it has been of great moment while the fight is going on, to disseminate words that pronounce the enemies' captain to be dead, or to have been conquered by another part of the army. Many times this has given victory to him who used it.

Before all else, be armed.

And the prince who has relied solely on their words, without making other preparations, is ruined, for the friendship which is gained by purchase and not through grandeur and nobility of spirit is merited but is not secured, and at times is not to be had.

If the chief party, whether it be the people, or the army, or the nobility, which you think most useful and of most consequence to you for the conservation of your dignity, be corrupt, you must follow their humor and indulge them, and in that case honesty and virtue are pernicious.

Any harm you do to a man should be done in such a way that you need not fear his revenge.

Men in general judge more from appearances than from reality. All men have eyes, but few have the gift of penetration.
