I used to try so hard to speed read books. Because of the reading challenge I set for myself.
The problem in the end was: I read the book, but retained very little.
I’m in the process of writing my “Books I read in 2016” blog post, and for some of them I just can’t remember anything.
In 2017 I will go for less books but more retention.
Disclaimer! It all depends on the type of book/content that you are reading.
Harry Potter is a speed read material! Think and Grow Rich is NOT! :)
