Why do many people hear so many truths but still can’t change? Because change has never been a cognitive problem, but an expectation problem. Long-term frustration, lack of control, and absence of positive feedback make the brain form an expectation that “effort is useless.” Once action and reward are disconnected for a long time, the brain actively reduces motivation to act, treating reducing consumption and avoiding further setbacks as a form of self-protection. Therefore, many people’s problem is not that they don’t know what to do, but that they no longer believe doing something will lead to results.
