aspects of writing I enjoy

What aspects of writing do I enjoy (most)?

[I wonder how many people going through these questions is the first initial response that I had choose something of the obverse of what E.B. White's character, Mr. Trexler, describes in Second Tree from the Corner when asked, "Have you ever had any bizarre thoughts?" . . .  He's completely scattered, anxious, feeling the pressure of the doctor's by, the doctor's position, the doctor's time . . .  . "Just reach into the bag and pick anything at all."]

•  perhaps it's a hazard of my occupation, but I'm thinking of the reward system in my brain, the idea that what I just did, that is, finding the connection between some previously encountered item (E.B. White's story), and something entirely different (this particular writing task I have at hand), and somehow fitting them together.  I think there are lots of pieces and feeling I was enjoying:
•  the initial reading and understanding of White's story,
• the activation of memory based on
• a new stimulus
• knowing how to retrieve the specific information is required going beyond just the recollection of the story and the paraphrase back down to
• accessing the Internet for the precise quote
• figuring out how to extract the best quote for the purpose
• knowing how to express that in writing in a way that communicates the precision of the quote ethically, fairly, accurately to the reader
•  [that went better than I thought it might have ;) ]
•  Then of course that's the joke we say about how being a professor and writing something down is more often than not about being "big me" versus "little you" . . . there can be a battle that occurs in writing
•  and now that I think, that battle occurs after the paper has been submitted, made of to face the battle with the  editors of the Journal interview process
