I totally relate to this article. In fact, I thought this was a characteristic of a writer.
I would say that intuition is an important gateway to conscious creativity as it works at a level beyond the everyday mind. The hallmark of intuition is immediate and direct knowledge without the conscious use of reasoning. Rising above thought but using the mind as a vehicle, intuition is a distinct sense of Knowing.
Most writers will have experienced intuition already even though they may not have been consciously aware that it was guiding them.
