We all fail,all the time.We might miss a call with a client because of an emergency work meeting,or miss that meeting because another project has suddenly become urgent.And then we (or our families) get sick,and we have to shift priorities around again.

    These unsystematic failures are benign,though.They reflect that all of us have limited resources.There simply is not enough time,energy,or money,to do everything you want to do all the time.Part of being a responsible adult is learning to make trade offs: balancing your conflicting goals and trying to get as much done as you can in the time you have.

    The thing you really need to watch out for is the systematic failure.The systematic failure happens when there's a particular goal you want to achieve,but never get to.The causes of systematic failures usually boil down to some combination of these three factors:

    1).Short-term pressures versus long-term goals.Most of us prefer to achieve pressing short-term goals rather than put time into long-term projects.Lots of research suggests that our brains are wired to prefer tasks that pay off in the short term rather than those whose benefit is long-term.The people who do manage to accomplish their long-term goals create regular space to make progress on them.

    2)._________Without even realizing it,we often do what is easiest to accomplish rather than what we say is most important.Email is a great example.If you are like most people,you keep your email program open at work all day. Consequently,each new message is an invitation to drop what you are working on to check it.It feels like work and it's much easier than finishing that 100-slide presentation.Simply shutting off email for a few hours a day can remove this source of distraction from the environment.

    3).Working for too long.Many workplaces create pressure to stay at the office for more and more hours,which (paradoxically) creates opportunities for systematic failures.Work is not an iron man competition where the last person there wins.Most people have an optimal（最佳的）number of hours they can work each day.For example,I can be productive at work for about 8-9 hours a day.If I spend any more time at work than that,then at some point,I start doing "fake work."

    The next time you run into trouble,assess whether it's an unsystematic failure or a systematic one.When you notice a systematic failure in your life,you need to make a change in your behavior.If you don't make a change,you will continue to fail.

    Finally,if you experience a lot of unsystematic failures,it might be worth rethinking the number of tasks you are taking on.Perhaps you need to offload some responsibilities onto someone else,before you start experiencing more systematic failures.

    Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who findsit.

    Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce Peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    An organization,Eye Care 4 Kids,is bringing much-needed eye care to poor kids.It provides free eye examinations for kids from poor families.Founded by Joseph Carbone in 2001,the organization has helped around 100,000 children in Utah and Nevada.

    Now,Cecil Swyers,a biomedical engineer who was once a poor child himself,is bringing the charity's services to poor students in Arizona,so that vision impairment（视力受损）doesn't stand in the way of their education.

    “Eye Care 4 Kids is bringing eye care and glasses to families that wouldn't have the means to pay for them,” said Mario Ventura from Isaac Elementary School District,the first school district in Arizona to receive its services.

    Good vision is important to a child's learning experience.According to a study,up to 80 percent of learning happens through sight for children between 6 and 18 years old.Without proper eye care,it's difficult for students to learn better and succeed.

    Swyers is hoping that by bringing the organization to Arizona he'll help a lot more students.He teamed up with two other organizations to get doctors to volunteer their time with the group.Using Eye Care 4 Kids mobile clinic,Swyers visited Alta E.Butler Elementary School and has already helped 40 students.

    The school was grateful to receive the eye care,especially since the services came to them.“It's is great for us,” said Assistant Pricipal Cindy Alonso.

    Swyers is hoping to bring Eye Care 4 Kids' services to other schools in the state.He said that hopefully his work will have a positive effect on students' futures.“If we can help students while they're young,we can make a difference in their futures,” he said.

    US people are overweight, eat lots of fast food and fill their homes with pets. At least that's what 21 European teenagers think.

    The students, 18 from Germany and 3 from France, are exchange students. They are studying in the US for a year. After a few days in the US, they said what they thought about the country.

    Most talked about the amount of fast food US people eat. It's not that the students don't eat fast food. They just don't eat as much.

    Laetitia Villeneuve from France said she eats fast food, usually McDonald's, only once or twice a year.

    "I like it," said Nora Koeberle from Germany. "But I couldn't eat it every day. I'd get fat. "

    Students are surprised at how big US people seem.

    "There are fat people in Germany," said Antonia Greimel from Germany. "But not as many as there are here."

    They also spoke about the animals. Silvana Wolfram from Germany said she had heard about how people had lots of pets in the US.

    Other ways of US high schools interested the students.

    For example, Koeberle said she wouldn't be able to play an instrument or sports as part of her classes in Germany. She can in the US.

    But the best thing about US high schools is something the European kids can't get back home. "I do wish we had parties," Koeberle said.

    Britain faces social problems as lots of people are set to lose their jobs in technological revolution, Bank of England's chief economist warned.

    Andy Haldane said the so-called Fourth Industrial Revolution will make the machine replace humans to do thinking things. The dark side of the change could be a much bigger breakdown of employment than in Victorian times, with professions such as accountancy (会计) among those at risk.

    A report by the accountancy firm PwC last month warned that more than 7 million jobs in Britain had been lost over the next 20 years as technological change sweeps though workplaces.

    The majority of these are in jobs in the retail, transport and manufacturing industries. However, other traditional professional sectors could also be at serious risk.

    Economists treat the arrival of increasingly intelligent computers and robots as the fourth industrial revolution. The first was the shift from agricultural to urban societies, the second saw the widespread use of electricity and steel, and the third was the digital revolution when computers, the Internet and mobile phones were developed.

    Mr. Haldane said the hollowing-out (空洞化) experienced in the past years could be on a greater scale in the future so it is important to learn the lessons of history and ensure that people are given training to take advantage of new opportunities.

    “Jobs were effectively taken by machines of various types, there was a hollowing-out of the jobs market, which left many people for a long period out of work and struggling to make a living,” Haldane added, “That heightened social and financial tensions, and led to a rise in inequality. This is the dark side of technological revolution.”

    “That hollowing-out is going to be potentially on a much greater scale in the future, when we have machines thinking and doing the cognitive and technical skills of humans.” Mr. Haldane said professions like accountancy could be among those hardest hit by the rise of AI. But he suggested economists could escape.

    Alison Malmon was trapping up (完成) the end of her freshman year at the University of Pennsylvania, US when she got the news: Her older brother Brian, a student at Columbia University, was suffering from mental illness.

    Inspired by this, Malmon formed a group at her university to empower (使能够) students to talk openly about mental health. It soon blossomed into a national organization that today has more than 450 campus chapters. Leaders with the organization spend their time talking with college students about the pressure that today's young people face.

    "What you hear often is just a need to be perfect," said Malmon, "and a need to present oneself as perfect."

    And a new study in the UK proved that this need for perfectionism is simply part of today's society. In the study, two researchers studied more than 40,000 students from the US, Canada, and the UK. They found that what they called "socially prescribed(社会定向型的) perfectionism" increased by a third between 1989 and 2016.

    Lead researcher Thomas Curran said that while so many of today's young people try to present a perfect appearance online, social media isn't the only reason behind this trend. Instead, he said, it may be driven by competition in modern society, meaning young people can't avoid being sorted and ranked in both education and employment. That comes from new norms(准则) like greater numbers of college students, standardized testing and parenting that increasingly emphasizes success in education.

    For example, in 1976, half of high school seniors expected to get a college degree of some kind. By 2008, more than 80 percent expected the same. The researchers also said changes in parenting styles over the last two decades might have had an impact. As parents feel increased pressure to raise successful children, they in turn pass their "achievement anxieties" onto their kids through "excessive(过多的) involvement in their child's routines, activities or emotions"

    Those in the mental health community like Malmon say they're concerned about the impact the culture of perfectionism has on mental health on campuses. "Mental health has truly become this generation's social justice issue," she said. "It's our job to equip them with the tools and to let people know that it's not their fault."
