Other people's views and troubles can be contagious. Don't sabotage yourself by unwittingly adopting negative, unproductive attitudes through your associations with others.

Confident because of our caution

A soul that makes virtue its companion is like an over-flowing well, for it is clean and pellucid, sweet and wholesome, open to all, rich, blameless and indestructible.

Silence is safer than speech.

Books are the training weights of the mind.

Bear in mind that you should conduct yourself in life as at a feast.

Let silence be your general rule; or say only what is necessary and in few words.
