Nobody lets you drive the car before you’ve proven you can bring the groceries in.

Responsibility is handed over in increments, and the increments are based on evidence rather than argument. Someone deciding whether to give you something larger is looking at how you handled the last small thing, which is a fair test even when it feels insulting. The small task is not beneath you; it is the only data available.

Do the unimpressive job properly and without visible resentment, since the attitude is half of what is being measured. Finish it before you are reminded. Then ask for the larger thing directly, because people rarely notice on their own that you are ready.
