解释：天地没有完美的功效，圣人没有完备的能力，万物没有完备的用途。

"To write is to breathe, and to breathe is to live."

The goal is not perfection but progress.

Make decisions when you are ready, not under pressure. Others will always push you to make a decision for their own purposes, internal politics, or some other external need. But you can almost always say, “I need a little more time to think about this. I’ll get back to you.” This tactic is very effective at defusing even the most difficult and uncomfortable situations.

可持续性还不够——我们需要再生。
