Let this be one invariable rule of your conduct--never to show the least symptom of resentment, which you cannot, to a certain degree, gratify; but always to smile, where you cannot strike.

Whatever you do, do it to the purpose; do it thoroughly, not superficially. Go to the bottom of things. Any thing half done, or half known, is in my mind, neither done nor known at all. Nay, worse, for it often misleads.

Choose the company of your superiors whenever you can have it.

Never seem wiser, nor more learned, than the people you are with. Wear your learning, like your watch, in a private pocket: and do not merely pull it out and strike it; merely to show that you have one.

Cautiously avoid speaking of the domestic affairs either of yourself, or of other people. Yours are nothing to them but tedious gossip; and theirs are nothing to you.
