Damn you! I wrote a bloody essay in a reply[1] to explain, in superfluous detail, what you summarized in one sentence. Anyone with basic knowledge of the topic would know what you mean. I need to figure out this magic people like you possess. I'm tired of rambling, when nobody will read it. Thank you for the incentive to improve.
That's the kindest spontaneous compliment I've received in a while. Thank you. But: while the pithy comment might farm more imaginary internet points, the essay may actually teach a lesson to the person who doesn't yet get it.
As for writing: it's not magic, but for me it's not consciously applied processes either. If I had to guess how my earlier comment came about, I'd suggest something like this as a generative process:
1. Find two effects with a common cause (provided upthread).
2. State each effect, sharing words and rhythm to bring out contrast.
3. Omit needless words. (Thanks, Strunk/White!)
