The last temptation is the greatest treason: to do the right deed for the wrong reason.

In three words I can sum up everything I've learned about life: it goes on.

"The past is never dead. It's not even past."

Don't be afraid of failure when facing challenges. Every failure is a step towards success.

Every setback is a setup for a comeback.

不要让昨天占据今天的太多时间。

不要轻易放弃，因为你永远不知道下一秒会发生什么。
