Evaluating the several basic aspects of creativity can help learners' develop a broader understanding of their creativity and could provide their with insights as to how to improve.

One important aspect of being creative is the ability to withhold judgment and to examine new and different ideas. Part of being creative is having tolerance to the unusual and for the ambiguous. This is often contrary to the skills valued in society or in a given field or domain.
