Friends can become enemies, and enemies can become friends. Ego and pride can turn what is good into bad, and kind words can turn what is bad into something good.

The best way to destroy your enemies is to make them adopt your worldview

Enemies and easy to get and even easier to keep. But friends are hard to get and even harder to keep.

Don't make the mistake of underestimating your enemies.

Not all things have to be scrutinized, nor all friends tested, not all enemies exposed and denounced

Lovers may be -- and indeed generally are -- enemies, but they never can be friends, because there must always be a spice of jealousy and a something of Self in all their speculations.
