Challenges are opportunities in disguise.

古人云：“欲工善其事，必先利其器。”要想把事情做好，首先必须要有便利的工具。

Reality is a question of perspective; the further you get from the past, the more concrete and plausible it seems—but as you approach the present, it inevitably seems more and more incredible.

重要的不是你被击倒多少次，而是你能重新站起来多少次。
