每一次技术突破的背后，都是无数次失败的积累。
Behind every technological breakthrough is the accumulation of countless failures.
"The truth is always more complex than we can imagine."
"The past never leaves us; we carry it in our eyes and in our voices."
The only lies for which we are truly punished are those we tell ourselves.
真正的英雄是有勇气说"不"的人。
