Make sure you don’t have any mental disorders that you aren’t aware of. Watch actual doctors (like Dr. K) on YouTube to figure this out. You’d be surprised how subtly a disorder can impact the rest of your life.

Do something more fulfilling. A decent chunk of the stuff you watch isn’t helpful and doesn’t satisfy you, so it’s probably better to watch some really good movies/videos/shows so that you give it your full attention. If that doesn’t work, find hobbies that do capture your attention.
