“When promulgating your esoteric cogitations or articulating your superficial sentimentalities amicable, philosophical, or psychological observations, beware of platitudinous ponderosities. Let your extemporaneous verbal evaporations and expatiations demonstrate lucidity and intelligibility without rodomontade or thespian bombast. Sedulously eschew all and sundry polysyllabic profundity, verbosity and vapidity. Abhor all double entendre, obnoxious jocosity, and pestiferous profanity observable or apparent.
In other words, state precisely that which you wish to say without the use of excessively large words"
