Truth

Love truth even if it harms you, and hate lies even if they serve you.

Believe what you see, and lay aside what you hear.

A known mistake is better than an unkown truth.

No land without stones, no meat without bones.

Friendship

Nothing dries sooner than a tear.

He who gives fair words feeds you with an empty spoon.

The enemy of my enemy is my friend.

Many are the roads that do not lead to the heart.

Contradictory

Don't cross the bridge until you come to it.

One who is not moved by words is not moved by sticks.

Many hands make light work.

Success

Exert Effort, you shall be rewarded

You can't catch two frogs with one hand.

Kill two birds with the one stone.
