A 10-Minute Practice Routine
- Two minutes: write the brief for a real task on your list.
- Three minutes: generate and read the result end to end.
- Four minutes: edit - real details in, generic lines out, opening rewritten.
- One minute: save the prompt and note one thing to change next time.
How to Know You Are Improving
