Judge of thine improvement, not by what thou speakest or writest, but by the firmness of thy mind, and the government of thy passions and affections.
Purchase not friends by gifts; when thou ceasest to give, such will cease to love.
If thou art a master, be sometimes blind; if a servant, sometimes deaf.
Search not a wound too deep lest thou make a new one.
Know most of the rooms of thy native country before thou goest over the threshold thereof.
