Humility is the solid foundation of all virtues.

Respect yourself and others will respect you.

How should I know anything about another world when I know so little of this?

Behind every smile there's teeth.

First and foremost, be faithful to your superiors, keep all promises, refuse the friendship of all who are not like you; and if you have made a mistake, do not be afraid of admitting the fact and amending your ways.

The man who asks a question is a fool for a minute, the man who does not ask is a fool for life.

I have not seen one who loves virtue as he loves beauty.
