The writer must be able to superintend himself and criticize himself.

"We live in a world where walls have ears and the ground has eyes."

In the depth of the valley is the road to salvation.

The human mind is designed to seek out and find evidence that confirms what it already believes.

我们永远要像充满好奇心的孩子一样，站在我们诞生于其中的的巨大奥秘面前，惊叹不已。

We must embrace the unknown in order to discover our true potential.
