Seeing that the nature of the prompt is personalized, I think that you are going to have to figure out for yourself how King's insight can help you in your academic writing. Speaking from a generalized perspective though, I think that one of King's most valuable insights is how he sees books. King says that “books are a uniquely portable magic.” This means that in order to become a better writer, one has to be a voracious reader. In advancing one's academic writing, it becomes evident that one must advance in their reading. The "portable magic" that is within books must be embraced in order to advance one's academic writing or any other genre of writing. King buys into the idea that writing instructor Nancie Atwell articulates: "Writers write reading and readers read writing." There is a reciprocal relationship between reading and writing. The "magic" within books invariably comes out in one's writing. In order to advance in academic or any other type of writing, enhancing one's reading is a must. King affirms this when he says, "If you want to be a writer, you must do two things above all others: Read a lot and write a lot." For King, the production quality of a writer is directly connected to how much they read. It is here in which reading different styles is something that King sees can enhance one's writing.
In the end, King argues that writing is a compulsion that exists within the writer, something illuminated with the author's discussion of Dumbo: "Just remember that Dumbo didn't need the feather; the magic was in him." This innate sense of magic is enhanced with reading different genres of writing. In cultivating the magic within the writer with "portable" forms of inspiration within books and reading, King's advice can help writers of academic content or any content.
