那么为什么我要谈论失败的好处呢？因为失败意味着剥离掉那些不必要的东西。我因此不再伪装自己、远离自我，而重新开始把所有精力放在对我最重要的事情上。
So why do I talk about the benefits of failure? Simply because failure meant a stripping away of the inessential. I stopped pretending to myself that I was anything other than what I was, and began to direct all my energy into finishing the only work that mattered to me.
