反事实路径 (Counterfactuals)

也就是心理学上的“如果当时……就好了”。当你对现状不满意时，你的大脑就会像单机游戏一样，用仅剩的算力在大脑里模拟出一条根本没发生过的路线来折磨你自己。这是一场彻头彻尾的内耗。

This is the psychological phenomenon of “if only I had…”. When you are dissatisfied with the present, your mind operates like a single-player game, consuming its remaining processing power to simulate a path that never actually occurred, thereby tormenting itself. It is a complete internal drain.
