Who has not served cannot command.
Night is the mother of thoughts.
Be circumspect how you offend schollers, for knowe, a serpent tooth bites not so ill, as dooth a schollers angrie quill.
Who hath not served can not command.
Who will not suffer labor in this world, let him not be born.
If you will be a traveler, have always two bags very full. That is one of patience and another of money.
