Create a small practice project with a clearly stated purpose and realistic limits. You might organize public information, write instructions for a familiar activity, or compare ways to explain a topic. AI can help generate alternatives, while you do the evaluation.
Label the result as practice rather than implying it was commissioned work. Keep a record of your choices, checks, and revisions. A transparent example can show how you approach a problem. It also gives you something concrete to discuss when seeking feedback or deciding what to learn next.
