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.

一个观念的效用决定了它在精神生活中的地位。

The only thing standing between you and your goal is the story you keep telling yourself as to why you can't achieve it.
