As I noticed, after reading 2-8 thousand words a day, after a few days of reading like this, it becomes very difficult for me to read, and I started reading actively lately, before that I only watched TV shows and movies, and now I have a slight headache, the text is floating, I even confuse words. In fact, that’s why I used to read very little, and now I’m so tired of TV shows and movies that I’m willing to force myself to read, even if I have a headache, to become emotionally attached to books instead of just consuming like zombie like I used to.
No shame in taking a break once in a while. Especially if this is new to you. You have to give your brain and eye muscles time to adjust.
Do something else when you feel like it’s getting too much.
