Choose your enemies carefully: you'll probably be known much better and far longer for who they were, than for anything else you ever managed to accomplish.
Choose your allies carefully: it's highly unlikely that you'll ever be held morally, legally, or historically accountable for the actions of your enemies.
Try never to speak of your enemies by name. Any publicity is still publicity - and there are those for whom your disapproval constitutes a recommendation.
Worse than thieves, murderers, or cannibals, those who offer compromise slow you and sap your vitality while pretending to be your friends. They are not your friends. Compromisers are the enemies of all humanity, the enemies of life itself. Compromisers are the enemies of everything important, sacred, and true.
Once you've taken a public stand you know is right, never back down; anything less than a rock-hard stance will let your enemies nibble you to death.
