小P第一次写博客

第一次写博客

NUMBER 0

接触csdn已经有一段时间了，大部分是查找资料，还真的在这找到不少的好东西，但对于博客这玩意儿，从来没尝试过，但我想尝试一下，而且定下一个长期的目标，整个的大学时光，多写写博客，多向大牛们学习，”Stay Hungry, Stay Foolish！”

NUMBER 1

第一次用markdown，不会，没事，慢慢学嘛(*^_^*)

NUMBER 2

不得不说，我是一个毅力不够的人，总是无法坚持下去，比如acm,比如健身，一方面是不知道从哪里开始，一方面是从内心深处有抵触的情绪，改变，才是人最难做到的事情，但我这个人的一个毛病就是不爱做太简单的事(。>︿<)_θ

NUMBER 3

我的目标是成为TOP 5%程序员，范围是the world!
其实我一直在考虑，这个目标的是不是会被人嘲笑，高了？低了？
哎，无所谓了，见过的白眼还少吗？

NUMBER 4

选择当一个程序猿，从某种程度上来说是必然的，尽管菜的抠脚，但却把技术当作忠实的信仰，脸厚点，我也要当大神，O(∩_∩)O！！！

注意：以上说的全是心里话啊，真的想要重新做人啊，对，就从今天开始(^_^)1

放一段自认为牛X的代码

（w(ﾟДﾟ)w不是我的）
