When one is tired of reading lengthy study materials, sometimes watching explanatory youtube videos is a good way to take a break, while still getting some studying done. The problem is, while some videos are informative, they are often at a very slow pace, some even more boring than plain text.
Recently my friend Ninad shared a simple trick with me to overcome this – he said to simply watch the videos at twice the speed. It works surprisingly well! Even the narration can still be understood. Use this one as an example: https://www.youtube.com/watch?v=UQ_8aPTydr4
For vidoes like these, ones that just give you a little bit of visual aid/ big picture rather than specific details, I think this is the way to go. Now you can be twice as efficient!
