Enemies to me are the sauce piquant to my dish of life.

The hatred of relatives is the bitterest.

All our enemies are mortal.

Revenge may be wicked, but it’s natural.

You shall judge of a man by his foes as well as by his friends.

I shall embrace my rival—until I suffocate him.

Enemies are so stimulating.

Rivalry is the whetstone of talent.

Better a thousand enemies outside the house than one inside.

Opposition may become sweet to a man when he has christened it persecution.

We often give our enemies the means for our own destruction.

When a coward sees a man he can beat, he becomes hungry for a fight.

The men of today are born to criticize; of Achilles they see only the heel.
