新手学编程要注意这些事情
今天在看编程类书籍的时候突然想到了这个问题，回顾自己的学习经历也走了好多的弯路，在不必要的事情上可能花了太多时间，虽说条条大路通罗马但是如果走的弯路太多一定会影响你的信心，事情到最后如果只剩下坚持，那太枯燥了….

Although that way may not be obvious at first unless you’re Dutch.
Now is better than never.
Although never is often better than right now.
If the implementation is hard to explain, it’s a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea — let’s do more of those!
