Never interrupt your enemy when he is making a mistake.
Napoleon Bonaparte
The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
Stephen Hawking
You have enemies? Good. That means you've stood up for something, sometime in your life.
Winston Churchill
He who has a thousand friends has not a friend to spare, And he who has one enemy will meet him everywhere.
Ralph Waldo Emerson
If you want to make enemies, try to change something.
Woodrow Wilson
Observe your enemies, for they first find out your faults.
Antisthenes
The enemy is within the gates; it is with our own luxury, our own folly, our own criminality that we have to contend
Marcus Tullius Cicero
When there is no enemy within, the enemies outside cannot hurt you.
African Proverb
Enemies make you stronger, allies make you weaker.
Frank Herbert
Pay attention to your enemies, for they are the first to discover your mistakes.
Antisthenes
Make the enemy live up to their own book of rules. You can kill them with this, for they can no more obey their own rules than the Christian church can live up to Christianity.
Saul David Alinsky
Never give in never, never, never, never, in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.
Sir Winston Leonard Spencer Churchill
