I'm working remotely now so it is indeed a self-reinforcing thing.
But the reason I work remotely now is that I was constantly being watched when working in offices and it burned me out very, very fast having to keep up the appearance of working after a 2-3h run, or else be penalized.
Then I work on one or the other entirely dependent on how I feel that day, so I'm productive even when I'm not mentally at 100%.
Good things for scutwork are documentation, updating dependencies, automating manual processes, checking backups, organising issues on the backlog etc, things I can comfortably do without requiring complete focus.
It definitely helps since I don't feel like I'm just present in front of the computer but getting things done (and things that are important to boot).
