I see this kind of distraction as introducing complication. When I was in high school about all I could do was listen to the radio on my boom box and even that was using too distracting.
Maybe another way to say it is that in high school math problems fit into a small enough chunk of memory that you could store it to disk and load it back into working memory in a few minutes.
On the other hand, I literally can't fit my current work project into working memory. It's just too big. I have to page it to stored notes. At the end of the day, I write to myself where I need to pick up the next day, and then the next day I spend 20 minutes following my notes to load that context back into working memory.
I don't think I'm bad at this stuff either, because my solo side projects don't have this problem. I can pick those up for an hour at a time and it's fine. But my work projects...
I suppose that’s because I insist on understanding more of the tech stack for my personal projects than I do for my work projects.
