Keep 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 ChesterfieldWear your knowledge like your watch - in you pocket - and don't pull it out just for show.
Lord ChesterfieldGreat merit or great failings will make you respected or despised; but trifles, little attentions, mere nothings, either done or neglected, will make you either liked or disliked, in the general run of the world. Examine yourself, why you like such and such people and dislike such and such others; and you will find that those different sentiments proceed from very slight causes.
Lord ChesterfieldThe power of applying attention, steady and undissipated, to a single object, is the sure mark of superior genius.
