Nothing is as dangerous as an ignorant friend; a wise enemy is to be preferred.
Be advised that all flatterers live at the expense of those who listen to them.
Everyone believes very easily whatever they fear or desire.
The more wary you are of danger, the more likely you are to meet it.
Example is a dangerous lure: where the wasp got through the gnat sticks fast.
Better a living beggar than a buried emperor.
