Growing up I really wasn't a fan of sitting and reading a book. To me it would just be words on a page, and often I would have to reread the same sentence multiple times and eventually feel drowsy. I recall being sat in the school library during some mandated reading time, and borderline falling asleep.
It wasn't until I was much older that I decided to give books another go. They are no longer words on a page to me, I now picture scenes with the characters. I don't know what changed it but I enjoy reading now, when I get the time. Maybe it was a change from it being almost a mandatory thing, to instead being my choice?
