All great points. Reading non fiction has absolutely changed my life.
There is one thing I would like to point out about fiction.
I layered fiction on top of my non fiction reading. Non-fiction was always my priority. But for the times that I was too tired to read more non-fiction, or if I wanted to turn my brain off, fiction was a great way to learn the skill of focusing when reading.
There are several challenges with reading. Tiredness/fatigue. Not knowing what to read. Not being able to focus with distractions. Feeling bored. Associating books with bad experiences in school (ie. testing).
Reading fiction along with non fiction is a great way to learn just the habit of, sitting down somewhere while not on social media or watching TV.
