When I teach flute lessons, I ask my students, "how did that feel?" after they finish playing part of a warm up, etude, or solo, often when it didn't go according to plan.
They figure the answer I'm looking for must be something external, so the first words out of their mouth are usually observations or judgments about what happened. But when I ask, "how did that feel?" I'm not asking about what could be judged externally, I'm asking about what you experienced internally.
