Let no one delay the study of philosophy while young nor weary of it when old.

Natural wealth is limited and easily obtained; the wealth defined by vain fancies is always beyond reach.

The greater the Difficulty the more Glory in surmounting it, and the loss of false Joys secures to us a much better Possession of real ones.

Nothing is sufficient for the person who finds sufficiency too little

Skillful pilots gain their reputation from storms and tempest.

He who needs riches least, enjoys riches most.
