A shrewd enemy will teach you more than a foolish friend.

Your father you esteem.
Your mother you pamper.
Your relatives you regard.
Your friends you value.
Your neighbors you respect.
Your enemies you pardon.

Learn from acquaintances, and you are clever;
from friends, and you are intelligent; from enemies, and you are shrewd; but learn from all, and you are wise.

If you step on everyone's toes, you will have no one to dance with.

Keep friends. Lose enemies. Multiply allies. Increase comrades.

When God is on your side, He uses the plots of your enemies to advance your cause.
