For ordinary people who scroll videos every day, the most important things to block are content that affects your emotions, makes you angry, causes fear, makes you feel inferior, makes you feel unfair, or pushes you to take sides, as well as news from mainstream media... The most worthwhile content to watch is about the future of technology, personal growth, children's education, awakening awareness, and the use of technology. Human attention is not about "receiving information," but about being shaped by information. A truly high-quality information structure should be: a small amount of real-world input + a large amount of growth input + long-term thinking.
