> I'm curious to see how you'd describe this distinction though.

One kind of "doing nothing" frees your mind to discover solutions and interesting ideas in a background process. Examples include talking a walk, talking a shower, or just sitting around and letting your mind wander.

The other kind of "doing nothing" occupies your mind with low-effort thought processes. Examples include watching TV or reading a book. This isn't necessarily a negative thing, but your mind won't be solving problems (unless you're not really focusing on the movie or the book).
