Before You Generate
- Write the goal in one sentence before you open the tool.
- Gather your real material first: facts, numbers, names and constraints.
- Decide what done looks like - length, format, tone and audience.
- Set aside five uninterrupted minutes; context switching costs more than the task.

Mistakes to Avoid
- Extracting by position when column order changed upstream
- Dropping a key column the import still needs
- Forgetting the header row in the output
- Removing columns that contain identifiers used elsewhere
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
Track edit time per result for two weeks. When it drops, your briefs are getting better. When it spikes, the cause is almost always a vague input - go back to the tip about writing the goal in one sentence.
