每日原则：现实为了整体趋向最优化，而不是为了个体

为整体做贡献，你就可能收获回报。自然选择让更好的品质得以保留和传承（如更好的基因、更好的养育他人的能力、更好的产品等）。结果是整体的持续循环改进。

Contribute to the whole and you will likely be rewarded. Natural selection leads to better qualities being retained and passed along (e.g., in better genes, better abilities to nurture others, better products, etc.). The result is a constant cycle of improvement for the whole.
