当每一分钱都要精打细算，犯错的空间就消失了。
When every penny must be calculated, the margin for error evaporates.
我不是来追求完美的，我是来诚实的。
A man of genius makes no mistakes. His errors are volitional and are the portals of discovery.
Covenants, without the sword, are but words, and of no strength to secure a man at all.
经济史告诉我们，改变是可能的，但很少是容易的。
以真诚之心待人接物。
