写作是一种乐观的行为。如果你觉得它不重要，你就不会费心去做。

I'm drawn to a lovely quote by St. Augustine in "The City of God," where he says, "It's a sin to judge any man by his post." In modern English that would mean it's a sinto come to any view of who you should talk to, dependent on their business card. It's not the post that should count. According to St. Augustine, only God can really put everybody in their place; he's going to do that on the Day of Judgment, with angels and trumpets, and the skies will open. Insane idea, if you're a secularist person, like me. But something very valuable in that idea, nevertheless.
