I am not the same person who walked in.

村上春樹《海邊的卡夫卡》/Haruki Murakami's Kafka on the Shore

而且當那沙風暴結束時,你可能還不太能理解,自己是如何穿過那風暴活下來的。不,甚至不太清楚那風暴是否真的已經走掉了。不過只有一件事你可以確定。那就是從那風暴中出來的你,已經不是踏進去時的你了。 
And once the storm is over you won’t remember how you made it through, how you managed to survive. You won’t even be sure, in fact, whether the storm is really over. But one thing is certain. When you come out of the storm you won’t be the same person who walked in. That’s what this storm’s all about. 
的確如此。我突然想起幾年前我聽過的一句話,「會有改變的人,都是一些沒有自信的人」。
Indeed. I suddenly thought of something heard from a couple of years ago -- "People who change are those lack of confidence".
