Were you to converse with a king, you ought to be as easy and unembarrassed as with your own valet-de chambre; but yet every look,word, and action should imply the utmost respect.... You must wait till you are spoken to; you must receive, not give, the subject of conversation, and you must even take care that the given subject of such conversation do not lead you into any impropriety.

Horse-play, romping, frequent and loud fits of laughter, jokes, and indiscriminate familiarity, will sink both merit and knowledge into a degree of contempt. They compose at most a merry fellow; and a merry fellow was never yet a respectable man.

When a person is in fashion, all they do is right.

You must look into people, as well as at them.

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

Wear your knowledge like your watch - in you pocket - and don't pull it out just for show.

Young men are as apt to think themselves wise enough, as drunken men are to think themselves sober enough. They look upon spirit to be a much better thing than experience; which they call coldness. They are but half mistaken; for though spirit without experience is dangerous, experience without spirit is languid and ineffective.
