Its true that we don't know what we've got until we loose it but it is also true that we don't know what we've been missing until it arrives.
的确，我们常常直到失去才知道自己拥有过什么；但是，也只有直到它出现，我们才知道一直以来缺少的是什么。

When one door of happiness closes, another opens but often we look so long at the closed door that we don't see the one, which opens to us.
当一扇快乐的门关上了，另一扇就会打开；但是我们常常死盯着那扇已经关上的门，而忽视了那扇对我们敞开的门。
