期望方程

打破成功学迷梦的底层数学公式。幸福感并不等于你的绝对财富值，而是等于“现实状态减去主观期望”。当你的收入是一万，但你的圈层让你觉得“应该”有十万时，这个公式输出的就是巨大的负数。痛苦，往往源于被外界恶意篡改的期望阈值。

The foundational mathematical formula that shatters the illusion of success: Happiness is not a function of absolute wealth, but rather the difference between one’s actual state and subjective expectations. When your income is ten thousand, yet your social circle convinces you that you “should” have a hundred thousand, the formula yields a profound negative value. Suffering often arises from the malicious external tampering of our expectation thresholds.
