Thoughts pass in my mind like flocks of lucks in the sky。I hear the voice of their wings。

读书人虽然有学问，但只有知行合一，把学问付诸于生活实践，才是最根本的。否则的话，就是《弟子规》上讲的“不力行，但学文，长浮华，成何人”了。

"Success is not final, failure is not fatal: It is the courage to continue that counts."

The truth is you don't know what is going to happen tomorrow. Life is a crazy ride, and nothing is guaranteed.

Life in the state of nature is solitary， poor， nasty， brutish， and short.
