[random advice from the internet]

I don't know how old you are, but my experience is of phases when I read less and phases when I read more and all of it depends on my interests.

Deep learning™ changes our interests...but we are culturally conditioned to a positivist (line go up) model of learning. Anyway, the periods where I read less are generally periods where I learning by doing (and the doing-learning is not learning writing).

For me, reading gets supplanted by self-motivated creative work requiring physicality. No matter how many books a person reads about dancing, reading books about dancing is not dancing (even if it is something a dancer might do).

recover from this rot

Nobody cares how many books another person reads unless they are being paid (e.g. teachers) or are the person's parents. Although reading can be imaginative, it is not creative. Nobody cares how many books JS Bach read except grad students desperate for thesis topics -- hopefully their committee will steer them away from that dullness.

Or to put it another way, give yourself permission to grow beyond what you believed growth looked like when you were younger. Good luck.
