"He who does not know how to create should not know"

This quote by Antonio Porchia suggests that those who do not possess the capability to create need to not even trouble trying. It implies that producing something, whether it be a masterpiece, a piece of writing, or perhaps a new idea, requires a specific level of skill and talent. Without this skill, trying to create something may lead to failure or frustration. Porchia may also be suggesting that those who do not have the capability to develop ought to concentrate on other locations of their life where they excel, rather than wasting time and energy on something they are not naturally talented at.
