To dispute with a drunkard is to debate with an empty house

A wise man will be the master of his mind. A fool will be it's slave.

Do not turn back when you are just at the goal.

Never thrust your own sickle into another's corn.

One ungrateful man does an injury to all who are suffering. [Lat., Ingratus unus miseris omnibus nocet.]

Union gives strength to the humble. [Lat., Auxilia humilia firma consensus facit.]
