子张问：“什么是五种美德？”孔子说：“君子对人民施加恩惠，却不耗费财用；使百姓劳苦，百姓却无怨言；自己有所欲求却不贪婪；安宁矜持却不骄横；威严却不凶猛。”……子张又说：“什么是四种恶行？”孔子说：“事先不经教育，犯了罪就杀头叫做肆虐；不先告诫便要求有成效，这叫粗暴；发布命令迟缓，却突然限期完成，这叫残害人；同是给人赏赐，却出手吝啬，这叫只进不出的财务衙门。

The best way to predict the future is to create it.
The best leaders are those who can see around corners and anticipate what's coming next.
Dream big, start small, act now.
"The day I stop improving is the day I should stop racing."
Dreams are the lighthouse that illuminates the way forward.
