Prove yourself with effort, not words.

幸福不是现成的东西。它来自你自己的行动。

用心体会整理才能理解精确得当，所以应当沉着稳重，不然就成了口头耳边的小事，过后就忘了。事理要以典故为依据，因此必须学识广博，否则就成了随意推测，胡编乱造。

最重要的是做自己并享受乐趣。

Zero-knowledge proofs are a way to prove that you know something without revealing what it is.

What I want to talk to you about today is the difference between gifts and choices. Cleverness is a gift， kindness is a choice. Gifts are easy -- they're given after all. Choices can be hard. You can seduce yourself with your gifts if you're not careful， and if you do， it'll probably be to the detriment of your choices.

自私性是一种自爱，怜悯心是一种他爱。一个人想要得到他人的爱，他自己首先应具备爱人之心。

我是行尸走肉，但我只是一个说话的脑袋，一个漂浮的僵尸，但我有一个地下兄弟。
