Concise, succinct, short, brief, to the point, pithy, incisive, short and sweet, crisp, abridged, condensed, compressed, abbreviated, compact, compendious, potted, in a nutshell, epigrammatic, aphoristic, terse, laconic, sparing, snappy, lapidary. I think none of these words could have ever been used for anything I wrote; I have tremendous respect for those who are able to express their thoughts clearly in a few words.
