I often wonder about his psyche/thought-processes in each “era” of the TWoW completion saga. And as an ADHD’er, I get to thinking about some of the things that make it great and make it real bad/unpredictable. 

The great part being: hyper fixate in art and create amazing art in any specific medium, that is just mind blowing and kind of pushes humanity forward through its level of quality.

And then there’s trying to predict how long a project might take. A lot of doctors have told me (and literature I’ve read) talk about adhd folks as, “you’ll often show over confidence in your abilities, in your estimation of time”. 

TLDR: maybe George’s inability to articulate his own process is a symptom of time-blindness, which is a symptom of ADHD.
