Many people's lives are ruined by "just for fun." At the bottom level, they scroll through short videos, only seeking emotional stimulation, not logic. A few seconds of a satisfying point, feeding their thought process into a straight line, and they lose their ability to think, apart from silly smiles and rage. The middle level watches news, thinking they have grasped the big picture. In reality, it's all "processed products" that others have chewed up, seasoned, and fed to them. What you see is only what others want you to see. What are true experts doing? They are "gnawing on raw meat." They read financial reports, examine source code, analyze data so dull it makes them want to vomit, and study obscure research reports that no one wants to read. Because in this noisy world, any information that is smooth, easy to swallow, or even makes you feel good has long been drained of its nutrients. Dullness is the true moat of the truth. Eating feed every day not only prevents you from growing fangs but also, when you end up on the chopping block, you have to blame the butcher's knife for being too fast.
