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 deeper the pain, the more profound the art.
Don't wait for the perfect moment. Take the moment and make it perfect.
"Man, unlike any other thing organic or inorganic in the universe, grows beyond his work, walks up the stairs of his concepts, emerges ahead of his accomplishments."
Mistakes can be corrected by those who pay attention to facts but dogmatism will not be corrected by those who are wedded to a vision.
