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, pompous prolificacy, and vain vapid verbosity.
In short "Be brief and don't use big words."
"Humility is a strange flower; it grows best in winter weather, and under storms of affliction."
"Mankind invented the atomic bomb, but no mouse would ever construct a mousetrap."

Thank You, GOD for everything
