I had limited education, limited skills and a limited future. And then I began asking, “ Why are some people more successful than others?” This question changed my life. Over the years, I have read thousands of books and articles on the subjects of success and achievement, It seems that one quality that most philosophers, teachers and experts agree on is self discipline (自律 ). Some years ago, I attended a conference in Washington. It was the lunch break and I was eating at a nearby food fair. The area was crowded and I sat down at the last open table by myself, even though it was a table for four. A few minutes later, an older gentleman came along carrying trays of food, obviously looking for a place to sit. With plenty of room at my table, I immediately arose and invited the older gentleman to join me. We began to chat over lunch. It turned out that his name was Kop Kopmeyer. As it happened, I immediately knew who he was. He was a legend (傳奇 ) in the field of success and achievement. Kop Kopmeyer had written four large books. I had read all four books from cover to cover, more than once. After we had chatted for a while, I asked him the question that many people in this situation ld ask, “ Of all the one thousand success principles that you have discovered, which do think is the most important?” He smiled at me with a twinkle in his eyes, as if he had times, and replied, without hesitating, “ The most important success principle of all was stated by Thomas Huxley many years ago. He said, ‘ Do what you should do, when you should do it whether you feel like it or not.’ ” He went on to say, “ There are 999 other success principles that I have found in my reading and experience, but without selfdiscipline, none of them work.” 24.

C Researchers at the University of Chicago have trained an artificial intelligence( AI) system to write fake(偽造的 ) reviews on Yelp, a website showing customers’ reviews on shopping or something else, and it39。s pretty hard to tell them apart from a human review Their study, which will be pressed at the ACM Conference on Computer and Communication Security in October, aimed to stress how easily these systems can write reviews like humans and how damaging they can bee if they re not mentioned properly. Since many small businesses rely on online reviews to help grow and support their reputation, a future where someonelike a petitor or angry customercould crazily fill their page with bad reviews written by a machine is pretty worrying. And, according to the research team, the threat (威脅 ) goes far beyond a bunch of fake reviews on Yelp. In general, the threat is bigger, Ben Y. Zhao, one of the authors of the study, said. “ I think the threat towards society is large and it really misleads users and shakes our belief in what is real and what is not. I think that’ s going to be even more unimaginable.” To test how believable these reviews came across, the researchers invited 40 volunteers and had AI generate(生成 ) five fake reviews for 40 actual restaurants. The volunteers were asked how useful they thought the reviews were and whether or not they thought they were fake. The Al reviews ranked as effectiv
