解决复杂问题的关键是提出正确的因果问题。

"We are all the sum of our memories, but what happens when those memories are erased or altered? Do we become someone else, or do we remain the same person, just with a different past?"

历史既没有愿望也没有能力使人变得更好或更坏；它仅仅记录了他们曾经是什么以及他们做了什么。

Keep pushing, keep believing, and never give up.

The cistern contains: the fountain overflows.

"Die Vergangenheit ist nie tot, sie ist nicht einmal vergangen."

People change and forget to tell each other.
