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.
Lord ChesterfieldPleasure is a necessary reciprocal. No one feels, who does not at the same time give it. To be pleased, one must please. What pleases you in others, will in general please them in you.
Lord ChesterfieldKeep your hands clean and pure from the infamous vice of corruption, a vice so infamous that it degrades even the other vices thatmay accompany it. Accept no present whatever; let your character in that respect be transparent and without the least speck, for as avarice is the vilest and dirtiest vice in private, corruption is so in public life.
Lord Chesterfield
