Julia Cameron points out that talented people can experience jealousy in different ways, some rather sneaky. Consider an artist not practicing their art to keep someone else from being jealous. Some of their reasoning?
“I don’t want to hurt (person’s) feelings.”
“I’d better not (make, paint, write something), and keep the peace.”
Cameron also refers to the jealous person as a crazy-maker because they will make an artist crazy. They will ~
“… break deals and destroy schedules… expect special treatment… discount your reality.. spend your time and money… triangulate those they deal with… are expert blamers… create dramas – but seldom where they belong… hate schedules – except their own… hate order… deny they are crazymakers…” (pp. 46-49, The Artist’s Way)
HOWEVER, she also outlines exactly how to deal with one’s own and others’ jealousies:
“Jealousy is always a mask for fear: fear that we aren’t able to get what we want; frustration that someone else seems to be getting what is rightfully ours even if we are too frightened to reach for it. At its root, jealousy is a stingy emotion. It doesn’t allow for the abundance and multiplicity of the universe… jealousy strips us of our will to act when action holds the key to our freedom.” (pp. 123-124, ibid.)
