You do not talk about the subject of your work or it vanishes
I am reading Joan Didion's book Let Me Tell You What I Mean and she wrote about the subject in creative work:
This business of the subject is tricky. Whether they are painters or photographers or composers or choreographers or for that matter writers, people whose work it is to make something out of nothing do not much like to talk about what they do or how they do it. They will talk quite freely about the technical tricks involved in what they do about lighting and filters if they are photographers, about voice and tone and rhythm if they are writers, but not about content. The attempt to analyze one's work, which is to say to know one's subject, is seen as destructive. Superstition prevails, fear that the fragile unfinished something will shatter, vanish, revert to the nothing from which it was made.
This is revealing for me that in the creative work that Didion is describing, there is an innate ephemeral quality, something beyond immediate grasp, something that is there but cannot be directly looked at.
