I know that in the art world many newcomers to it say that they cannot create art, when what they mean is that they cannot draw something that aspires to a photographic ideal of fidelity to detail, or that they would simply not want to learn such skills. Yet they can maybe do something which is highly expressive anyway, in part by its very simplicity. One might explain to such a person that they don't have to strive for photographic realism, as we have cameras for that.
A friend of mine is a teacher and she has told me about teaching people how to learn as well as teaching them subjects that they would apply such learning skills towards. Some teachers only concentrate on the latter.
