Writing is not just capturing a thought. It's also capturing the thought well—what I call "capturing the beast." A writer may develop the habit of writing certain thoughts over and over: searching for a good, true expression.
I'm not convinced it's possible to be a decent writer without this habit. While admittedly I have little in the way of scientific proof, from what I've heard and read, creative types often produce tremendous amounts more than they share as final. The repetition is preparation.
It's frustrating for a creative person to get stuck in the same loop. You want to move on to something new, better. But you know you haven't captured the beast yet.
