你唯一应该努力超越的人就是昨天的自己。

Just be yourself, there is no one better.

每一次挫折都是为了卷土重来做准备。

即使没有其他人相信你，也要相信自己，因为那是最重要的时刻。

I never write Metropolis for seven cents because I can get the same price for city. I never write policeman because I can get the same money for cop.

The best way to predict the future is to create it.
