My dad reads about the same level as you do. My wife reads about the same speed as she speaks. I am probably half the speed as my father at my peak. I have found out that my dad really isn't a details person. Sadly I am more of a global view first then details and I have to process stuff into that global view all the time. Being a Theological student in grad school I would have about 2,000 to 12,000 pages of reading per class. UGH took me forever to learn how to up my speed and my retention.
It used to be a huge concern for me as well. I realized that the more I read, the faster I read. So if you are worried about reading speed, don't. Just read, and it will get better. With no extra effort from me, my reading speed increased by at least 50% since I started reading books seriously.
Conditions allowing that:
- I nearly always read on my phone.
- I can read on my commute.
- I read before going to sleep.
- I read quickly.
