Most people want to read more books, but this video is about How to Read Fewer Books. Well, it's about reading more effectively, instead of reading for the sake of reading.
Here is a video by a certain John Fish about How to Remember What You Read: (1) read with a pen in your hand and take notes; (2) use the Feynman technique; (3) after finishing the book, put the most important ideas on cards and file them alphabetically.
@APerspicaciouslyCuriousMind That makes more sense :-)
