There you are, the world is a jungle of words and you can’t find one; the one you’ve been searching for: the right one. Let me beam a light on this dilemma.
You are this origami prose writer: a sculptor of words. For you, it’s not the length of the piece. No, this is entirely about content. You know that in a hostage situation your commander does not want details of what you had for breakfast; who you bumped into after that or what was headlining on the news stand. He wants immediate, accurate intel to extract that trapped word that needs all the brief wit training invested in you to release it in short measure. Now that’s what I call exercising your write. No need for all that circumventing. Just vent.
I hope that’s clear and precise enough for you. Now prose.
