There is nothing as likely to succeed as what the enemy believes you cannot attempt.
Niccolo Machiavelli....it cannot be called ingenuity to kill one's fellow citizens, to betray friends, to be without faith, without mercy, without religion; by these means one can aquire power but not glory.
Niccolo MachiavelliIt should be borne in mind that there is nothing more difficult to arrange, more doubtful of success, and more dangerous to carry through than initiating changes. The innovator makes enemies of all those who prospered under the old order, and only lukewarm support is forthcoming from those who would prosper under the new. Their support is lukewarm ... partly because men are generally incredulous, never really trusting new things unless they have tested them by experience.
