Now, I am not going to stand here and tell you that failure is fun. That period of my life was a dark one, and I had no idea that there was going to be what the press has since represented as a kind of fairy tale resolution. I had no idea then how far the tunnel extended, and for a long time, any light at the end of it was a hope rather than a reality.

The truth is, we know so little about life, we don't really know what the good news is and what the bad news is.

"Die größte Gefahr ist die Gleichgültigkeit."

我不让错误定义我，我让它们磨砺我。

"A story has no beginning or end: arbitrarily one chooses that moment of experience from which to look back or from which to look ahead."
