期望过高，可能会遇到难以承受的断崖；
期望过低，可能逐渐失去生存的欲望。
阴阳融合乃至中庸之道。
The way your progress toward a goal creates an entirely new identity.
人总是处在变化之中，小时候的你可能想成为宇航员；毕业工作的你可能只想在家里摆烂。我们永远无法达到「理想状态」，我们在变，理想在变。It’s impossible to Reach the stage of Enough
Many World aka Parallel Universe or Multiverse 也许可以参考「多重宇宙理论」，我们所做的 A/B 两个选择会使得我们进入不同的两个线性宇宙中。
Each time when we progress, we create a new identity, and the goal will change along it.
Enough is elusive because when you reach it, you’re no longer the person that once desired it.
最理想的情况是，在人生的成熟阶段，我们让目标在某个区间波动，并保持上进心和谦卑之心；而不是始终追寻着一个无法达成的梦想，或者认为这一切其实「毫无意义」。
You must self-adjust your definition of enough, instead of having it forced upon you. Wisdom is in self-correction, while misery is in coerced correction.
