Whenever you learning something new, you should also ask yourself whether it is useful. Remember, everything you do has an opprotunity cost - it prevents you from doing something else that might be more useful.
World-class performers spend most of their time practicing moves and techniques that fall beyond their comfort zone. Meanwhile, average people spend most of their time trying to polish existing skills.
The less effort you exert - reading a book passively, watching a video while doing something else, et cetera - the less you're really learning. Inversely, the more effort you make - taking notes using your own words, summarizing the content in your head, recalling key concepts, et cetera - the more you're learning.
