How laudable it is for a prince to keep good faith and live with integrity, and not with astuteness, every one knows.

Niccolo MachiavelliWar is a profession by which a man cannot live honorably; an employment by which the soldier, if he would reap any profit, is obliged to be false, rapacious, and cruel.
Niccolo MachiavelliAll courses of action are risky, so prudence is not in avoiding danger (it's impossible), but calculating risk and acting decisively. Make mistakes of ambition and not mistakes of sloth. Develop the strength to do bold things, not the strength to suffer.
