Fortune never helps the fainthearted.
Not knowing anything is the sweetest life.
How terrible is wisdom, when it brings no profit to the man that's wise
Who feels no ills, should, therefore, fear them; and when fortune smiles, be doubly cautious, lest destruction come remorseless on him, and he fall unpitied.
Trust dies but mistrust blossoms.
Be a thrifty steward of thy goods.
