Be careful to leave your sons well instructed rather than rich, for the hopes of the instructed are better than the wealth of the ignorant.

Do not seek to bring things to pass in accordance with your wishes, but wish for them as they are, and you will find them.

He is a wise man who does not grieve for the things which he has not, but rejoices for those which he has.
