Any problem in computer science can be solved with another layer of indirection.

如果你不前进，你就在落后。

史记

布施出去的很少，希望得到的回报却很多，这样的话，别人就不敢接受你的布施了。

"In computational learning theory, the challenge is not just to learn, but to understand how learning is possible."

君子以品德不修为耻，不以被污蔑为耻；以不诚信为耻，不以不被信任为耻；以无能耐为耻，不以不被任用为耻。
