Calling someone naturally talented can describe the impression their work creates without explaining how they became capable. For your own development, a more useful question is which part of the performance can be practised.
Break the skill apart
A strong presentation includes structure, clarity, pacing and handling questions. A strong campaign includes research, positioning, execution and evaluation. Choose one component instead of trying to improve the whole discipline at once.
Use a task that exposes the skill. Re-reading advice about writing is different from rewriting a confusing paragraph and testing whether someone understands it.
Make feedback specific
Ask what worked, where the result failed and what should change on the next attempt. Feedback is easier to use when it refers to the actual output rather than a broad judgement about ability.
Repetition alone can make a weak method more familiar. Include enough feedback to know whether you are repeating a useful action.
Increase the challenge gradually
Once the task becomes comfortable, add a relevant constraint: a clearer brief, a different audience or less assistance. Keep the difficulty high enough to reveal a gap without making every attempt impossible to assess.
Review the trajectory
Compare recent work with earlier work using the same criteria. Progress may be uneven and some skills may need outside instruction. The point is not to deny differences in aptitude or opportunity. It is to focus your effort on the parts you can change instead of waiting to feel like the kind of person who is allowed to be good at the work.
