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
- Assuming complementary always means readable
- Pairing two fully saturated colours and overwhelming the eye
- Ignoring lightness when both colours are mid-tone
- Treating the rule as mandatory
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.
