Keep it simple, stupid

Most systems work best if they are kept simple rather than made complex.

大部分的简单的系统相对于复杂的系统,是能够更加良好的运行的.

Why?
Less code takes less time to write, has less bugs, and is easier to modify.
Simplicity is the ultimate sophistication.
It seems that perfection is reached not when there is nothing left to add, 
but when there is nothing left to take away.

1.代码越少,bug越少,并且系统也更加容易进行修改.
2.简单,才是最终的追求
3.对于一个系统而言,完美并不是这个系统没有什么需要添加的了,而是他没有什么需要删除的了
