人需要三项很重要的能力：坚持不放弃直至成功的能力，能够放弃不对的事情的能力，以及能够信任他人来帮助你鉴别以上两种情况的能力。
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.
我们都在阴沟里，但有些人却在仰望星空。
"We are all broken by something. We have all been hurt by life in some way. But we can be mended. We can be made whole again."
The fountain of content must spring up in the mind, and they who have so little knowledge of human nature as to seek happiness by changing anything but their own dispositions will waste their lives in fruitless efforts.
