Diagnose why you've stopped improving at something and get a plan to break through the plateau. Use when asked I've stopped getting better at, I'm stuck at the same level, how do I improve past this plateau, or why am I not improving. Produces a diagnosis of why you've plateaued (comfort-zone practice, missing feedback, a specific weak sub-skill, or just needing recovery), the specific change that resumes progress, a targeted practice plan for your actual bottleneck, and honest expectations — because plateaus are usually a practice problem, not a talent ceiling.
