模型只是模型，而非事物本身。你无法吃掉菜单，无论描述多么准确。

I’d tell men and women in their mid-twenties not to settle for a job or a profession or even a career. Seek a calling. Even if you don’t know what that means, seek it. If you’re following your calling, the fatigue will be easier to bear, the disappointments will be fuel, the highs will be like nothing you’ve ever felt.

真相并不总是我们想听的，但它是我们需要知道的。
