When I was a young college student my professor said “there’s one book, and if you read it, it will change how well you do in college. It’s called ‘How To Read A Book.’”
I was shocked. Of course I know how to read a book. I made it to college after all. Curiosity got me and I checked it out from the library and read it. Turns out, I didn’t know how to read a book. :)
If you’re looking to get back into reading that book is a good start.
