真正的护城河是用户对你的依赖。

"The act of writing is an act of optimism. You would not take the trouble to do it if you felt it didn't matter."

If you're going to innovate, you have to be willing to fail. If you're going to try new things, then you have to be willing to accept that you might fail.

真相往往被隐藏，揭开它需要勇气。

希望好像一个家庭，没有它，你会觉得生活乏味；有了它，你又觉得天天为它辛劳，是一种烦恼。
