Agreed. That's how I was trained, at least. Although the end goal is to quiet your mind and gain more control over it, to think of one thing instead of a bunch of crabs on a string scuttling everywhere. So you could sort of sum of the end goal of a quiet mind as "think of nothing" but the one current thing...I'd definitely prefer other wording.

If you imagine your thoughts as a directed graph of associations, it's clear that the only way to stay in one place is with a thought that links back to itself. Otherwise, you'll go off along some tangent and end up elsewhere.
