学习Lisp是值得的，因为当你最终理解它时，你将获得深刻的启蒙体验；这种体验将使你在余下的日子里成为一个更好的程序员，即使你实际上并不经常使用Lisp本身。
Lisp is worth learning for the profound enlightenment experience you will have when you finally get it; that experience will make you a better programmer for the rest of your days, even if you never actually use Lisp itself a lot.
The past is full of voices—we just have to listen.
我们拥有的最伟大工具是我们心灵的力量。

眼睛是什么也看不见的，应该用心去寻找。
