Hmmmnnnnn. . . . From my experience in this creative industry. When I got stuck in the rabbit hole of doing the same work over and over again, just like Wakaba-san I also tend to lose the focus of the work which most likely lead the domino effect to felt like infinity revision.
And I found, one of the best way to get myself out of the rabbit hole is . . . by not doing the work at all. Stepping out, get some fresh air or different environment for some time. My sup used to say Id better spend my time sleeping or taking a shit rather than keep working overnight with a stressed mind. So when we got back, we can work with a refreshed mind.
Tho I do realize it's not a luxury we can always have. Sometimes the deadlines say a big flat NO. But I was really hoping this chapter would show us how important rest is, since we've been shown they have been working like nonstop. Remember they have a full-time job which takes a toll in daytime already.
Even machines need rest and maintenance.
