唯一真正的监狱是你为自己建造的那个。

对任何思考者来说，最大的挑战是以一种允许解决的方式表述问题。

Every decision we make underground has an impact above ground—that's the weight we carry.

我看到了，我忘记了；我听到了，我记住了；我做过了，我理解了。

"To live is to be haunted by the ghosts of what might have been."

I don't think about the past. The only thing that matters is the future.

即使不完美，也很美。
