Watched my own numbers do the exact same thing last spring. I spent almost a year doing fancy edits with zoom cuts and sound effects, and my best video in that whole stretch got like 700 views. Then I filmed one where I just sat on my couch and answered a question about why I stopped doing a certain type of video, totally unscripted, and it blew up to 40k. What I noticed was the comments changed, people were actually talking to me instead of just watching, and that kept feeding the thing. Looking back I don't think it was luck, I think people can tell when you're putting on a show versus when you're just talking to them like a person. The hype edits got clicks maybe but they never got replies, and replies are what push a video out. That boring tax breakdown thing probably hit because somebody asked for it, so the people watching already wanted that exact thing.

Been there man. I did the same thing with Moby Dick, blew through it in a week and then my wife asked what it was about and I just stared at her. Total blank. You get in this mode where your eyes are moving but your brain is just waiting for something to happen. What helped me was reading out loud for a few pages a day, like actually hearing the words. Sounds dumb but it forces you to stop and sit with the sentences. Also try reading something way slower than you think you should. Like painfully slow at first.
