政就是正的意思。如果你能带头走正道，谁还敢不行正道呢？

"The past is a burden we carry with us, shaping our present and future in ways we cannot always understand."

不要为短期利益而牺牲你的诚信。

"The major threats to survival that our ancestors faced - predators, starvation, disease - left their mark on our fears and anxieties."

一个好的统计分析就像一瓶好酒：需要时间、耐心和细心的处理。
