I consider it a mark of great prudence in a man to abstain from threats or any contemptuous expressions, for neither of these weaken the enemy, but threats make him more cautious, and the other excites his hatred, and a desire to revenge himself.
I assert once again as a truth to which history as a whole bears witness that men may second their fortune, but cannot oppose it; that they may weave its warp, but cannot break it. Yet they should never give up, because there is always hope, though they know not the end and more towards it along roads which cross one another and as yet are unexplored; and since there is hope, they should not despair, no matter what fortune brings or in what travail they find themselves.
A prince is also respected when he is a true friend and a true enemy; that is, when he declares himself on the side of one prince against another without any reservation.

For a prince should have two fears: one, internal concerning his subjects; the other, external, concerning foreign powers. From the latter he can always defend himself by his good troops and friends; and he will always have good friends if he has good troops.
In the armies and among every ten men there is one of more life, of more heart, or at least of more authority, who with his courage, with words and by example keeps the others firm and disposed to fight.
