不好的事情会经常发生。

True progress is measured not just in yields, but in the positive impact we create.

译文：人心就像天空和深渊。心的本体，无所不包，原本就是一个天。只是因为被私欲所阻碍，那么天的本体就丧失了。心中的道理无穷无尽，原本就是一个深渊。只是因为被私欲堵塞，那么深渊的本体就丧失了。

Challenges are opportunities in disguise; embrace them with courage.

How wonderful that we have met with a paradox. Now we have some hope of making progress.

I think it's important to have a positive attitude and to be optimistic.
