One of the things I did most obsessively before the brain surgery was make lists. As anyone knows who has read this blog before the surgery, or for that matter most of my books.
The ways I made them varied, but the most common were alphabet lists, because that made them easy to remember, at least for me, The other most common way was to make trinity lists. Being raised Irish Catholic, there were a lot of trinities in my youth, from the shamrock and Jesus, Mary and Joseph to The Holy Trinity themselves.
But I've been unable to finish any list making that comes to mind, or remember later even the partial attempts I have made. So one of these days I'm going to just make a list in a post, not one that's in my head when I'm falling asleep or taking a walk in the park or etc.
I've been compulsively making lists since I could write, so it's been a very strange hiatus for me. I have the urge, but I just can't remember not just the names of whatever comes to mind to write a list of, but the whole point (or even pointlessness) of the thing. My mind just drifts into other subjects and ways of thinking about things.
As usual, I find this pretty fascinating, since it's my mind, and the change is so drastic and there's nothing I can, or want for that matter, to do about it except observe it as it happens and think about the mysteries of the brain and the ways it works and organizes thoughts. Hmmmm.
