I used to be a visualizer. At around the age of 8-12 I could imagine a movie in my mind as I read. Once I read an entire 500 page book, one which was relatively high level for and 8 year old, in a single day. Unfortunantly, I don’t to do that anymore despite being an older, more experienced reader. I slowly push the pages and subvocalize. it takes me a few weeks to read 500 pages. I don’t know what changed my mindset. It’s a lot less satisfying to read this way. Does anyone have tips about how to active a mental movie while reading?
You’re slow because you’re out of practice. The more you read, and read consistently, the more you’ll get better on focusing on the book and tuning out distractions.
