出自汉·桓宽《盐铁论·执务》。土地堆积起来，便成为山峦。水储存起来便会形成江海，品行积累起来便会成为高尚的人。

The act of writing is an act of optimism. You would not take the trouble to do it if you felt it didn't matter.

I think it's very important to have a feedback loop, where you're constantly thinking about what you've done and how you could be doing it better.

你以为早上醒来昨天就不算数了。但昨天才是真正算数的。还有什么呢？你的生命就是由那些日子组成的。没有别的。

过去从未消逝，它甚至从未过去。
