I realized how long I watched YouTube videos, I don't learn any new knowledge. I can learn a little about things I already know enough, or I can grasp overview of new topics, but it's never enough to use in actual conversations. The worst part is the false sense of improvement. IMO, Learning nothing, yet feeling a sense of improvement is worse than learning nothing at all.
