"Understanding the limits of computation is as important as understanding the limits of mathematics."
I have a vivid memory of what happened， and it was not what I expected. I expected to be applauded for my cleverness and arithmetic skills. "Jeff， you're so smart. You had to have made some tricky estimates， figure out the number of minutes in a year and do some division." That's not what happened. Instead， my grandmother burst into tears. I sat in the backseat and did not know what to do. While my grandmother sat crying， my grandfather， who had been driving in silence， pulled over onto the shoulder of the highway. He got out of the car and came around and opened my door and waited for me to follow. Was I in trouble？ My grandfather was a highly intelligent， quiet man. He had never said a harsh word to me， and maybe this was to be the first time？ Or maybe he would ask that I get back in the car and apologize to my grandmother. I had no experience in this realm with my grandparents and no way to gauge what the consequences might be. We stopped beside the trailer. My grandfather looked at me， and after a bit of silence， he gently and calmly said， "Jeff， one day you'll understand that it's harder to be kind than clever."
可持续性不是选择，而是我们对下一代的责任。
我当时在纽约一家金融公司工作，同事是一群非常聪明的人，我的老板也很有智慧，我很羡慕他。我告诉我的老板我想开办一家在网上卖书的公司。他带我在中央公园漫步良久，认真地听我讲完，最后说："听起来真是一个很好的主意，但是对那些目前没有谋到一份好工作的人来说，这个主意会更好。"这一逻辑对我而言颇有道理，他说服我在最终作出决定之前再考虑48小时。那样想来，这个决定确实很艰难，但是最终，我决定拼一次。我认为自己不会为尝试过后的失败而遗憾，倒是有所决定但完全不付诸行动会一直煎熬着我。在深思熟虑之后，我选择了那条不安全的道路，去追随我内心的热情。我为那个决定感到骄傲。
玩家骂你是好事，说明他们还在乎。最可怕的是沉默。
质量和道德永远不应该为短期利益而妥协。
