Three things you need: The ability to not give up something till it works, the ability to give up something that does not work, and the trust in other people to help you distinguish between the two.
你必须具备的三种能力:在确认一件事情能运作之前永不言弃的能力，在确认一件事情无法工作下去时放弃他的能力，以及信任能帮助你区分二者的人。
别哭了，我很抱歉，你一定要明白，我很抱歉骗你这么多，但生活就是如此。
I'm a fighter, I don't give up.
Every artist is a cannibal, every poet is a thief. All kill their inspiration and sing about the grief.
