Tudo vale a pena quando a alma não é pequena.
当灵魂不渺小时,一切都值得。
在所有的动物中,只有人类是残忍的。他们是唯一将快乐建立在制造痛苦之上的动物。
感恩释放了生命的丰盛。它将我们所拥有的变成足够,甚至更多。它将拒绝变成接受,混乱变成秩序,困惑变成清晰。它可以将一顿饭变成盛宴,一所房子变成家,一个陌生人变成朋友。
Patience and tenacity of purpose are worth more than twice their weight of cleverness.  
The real problem is not whether machines think but whether men do.
