This right here. As a kid all the way up through highschool, I was an avid bookworm. I absolutely loved to read. I was reading 4-500 page novels by 6th grade and getting through them pretty quick.

But when I got into college, I had to read a bunch of boring textbooks for a degree that I have never even used. My focus started drifting more and more every time I read anything.

Now it takes me so long to get through a book, even if I'm interested in it, because my mind will drift and I'll have to go back and reread the same page 5 times before I actually retain what it says.

Pretty similar thing happened to me, loved to read until we started getting these lessons in Secondary school where we had to sit for an hour and read, which would have been fine but the book had to be on this system they had so it could be logged, and you had to do a little test on it to prove you read it, and if had to match your "reading age" There were so few books I wanted to read on the system that they actually had in the library so I just had to read loads of books I didn't enjoy, and suddenly reading became a chore and if became harder and harder to finish a page over time. 

Now I havent read a book all the way through in years
