People can keep moving upward, but an almost overlooked premise is: your total energy is fixed. You simply don't have extra strength to defend downward while growing upward at the same time. As long as you keep being vigilant around you, analyzing human nature, and reinforcing that layer of self-protection, your energy will always be locked in a defensive posture. Those forces that should be used for突破、创造、成长 are consumed by continuous reactions to the environment. The malicious density of your environment directly determines your maximum state—whether you invest all your effort into self-development or are forced to spend everything on defense and counterattack. An important realization after adulthood is that you must actively identify and strip away environments that require you to stay tense and repeatedly prove yourself. You need to clear-headed, even coldly, find and build a living space that does not drain you or target you. Like migratory birds, you must proactively and accurately fly to a habitat where you can put down your guard and spread your wings.
