In promulgating your esoteric cogitations or articulating your superficial sentimentalities, and amicable philosophical or psychological observations, beware of platitudinous ponderosity. Let your conversational communications possess a compacted conciseness, a clarified comprehensibility, a coalescent cogency, and a concatenated consistency. Eschew obfuscation and all conglomeration of flatulent garrulity, jejune babblement, and asinine affectations. Let your extemporaneous descantings and unpremeditated expatiations have intelligibility and voracious vivacity without rodomontade or thrasonical bombast. Sedulously avoid all polysyllabic profundity, ompous prolificacy, and vain vapid verbosity.
In short: "Be brief and don't use big words."
