People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can't focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.

    Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants' multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.

    Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.

     “People multitask not because it's going to lead to greater productivity, but because they're distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.

    Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn't find out whether people who start out less focused tend toward multitasking or whether people's recognizing and understanding abilities change as a result of multitasking.

    The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they're dangerous.”

    Feeling sad is an important part of human nature.

    Jerome Wakefield, a professor at New York University, mentions that feeling down after your heart is broken is normal and may even be beneficial. Recently, Wakefield's students have been coming up to him because their parents are pressuring them to get help for their sadness; often the kids want no part of it. Rather than “listen to medicine,” they want to listen to their hearts. He believes these students' reaction represents an important part of human nature.

    Professor Diener, who has studied happiness for a quarter century, finds that the Scots and many other peoples like being sad, and don't appreciate being told they should be happier. “They say too much happiness might not be such a good thing, no matter where it comes from,” says Diener. He believes it's wrong for the “happiness industry” to send the message that not only can we all be happier, but we have a duty to be so. He argues that what is considered normal sadness is something we shouldn't avoid.

    Eric Wilson, a professor at Wake Forest University, made every effort to smooth out his habitual frown and wear a sunny smile, since a happy expression can lead to happy feelings. He even tried to be enthusiastic. When neither of these made him happy, he concluded that such a happiness movement was no good for him at all. Americans, love for happiness, he writes, creates an environment where sadness is not valued.

    These researchers believe the problem of continuous, extreme happiness should not be surprising, since negative emotions developed for a reason. Fear warns us against the presence of danger, for instance. Sadness, too, seems to be part of our DNA: monkeys, dogs and elephants all display something that looks like sadness. Being “up” all the time can cause you to play down very real threats.

    They believe that only by experiencing sadness can we experience the fullness of the human condition. Their studies show that when you are in a negative frame of mind, you become more logical and more creative. Abraham Lincoln was not limited by his dark moods, and Beethoven composed his later works in a sad state. Vincent van Gogh, Emily Dickinson and other artistic giants saw the world through a glass darkly.

    People who are somewhat unhappy are more motivated to improve both their own lot and the lot of their community. In contrast, people at the top of the happiness charts feel no such urgency. “If you're totally satisfied with your life,” says Diener, “you don't feel like working for change. Be careful when people tell you that you should be happier.”

    The impression you make at the beginning of an interview is very important. Employers often decide to hire someone in the first three minutes of the interview. They judge you by your appearance, attitude and manners.

    A friendly smile when you walk into the room is important. A smile shows a confident and positive attitude.

    When you introduce yourself, make eye contact with the interviewer. Some interviewers offer a handshake. Others don't.

    Try to be as natural as possible. But pay attention to your body language. The way you sit, walk, gesture, use your voice and show feelings on your face is all part of your body language. It makes the interviewer know how you feel about yourself and the situation you are in. Are you feeling positively about yourself? Your abilities? Your interest in the job?

    Speak clearly and loudly enough. Show interest and enthusiasm in your voice. When you speak, look at the interviewer. Also, don't say negative things about yourself, or former employer.

    Listen to questions carefully. If you don't understand a question, ask the interviewer to repeat or explain:

    "I'm sorry, but I didn't catch that."

    "I'm not sure exactly what you mean."

    Almost everyone is nervous in a job interview. Interviewers know that. They don't expect you to be totally calm and relaxed. But they expect you to try to control your nervousness. They expect you to show confidence in your ability to do the job.

    At the end of the interview, thank the interviewer for her or his time.

    It's a good idea to send a short thank-you letter right after the interview, or deliver it by hand.

    Phone the company if you have not heard anything after one week. Ask if they have made a decision about the job.

    Good luck!

    Better known by his stage name KUN, Cai Xukun is a phenomenon, opening up the music industry in China.

    Last year, after participating in the reality TV show Idol Producer, receiving the most votes from fans, the singer-songwriter rose to fame overnight. At just 21 years old, Cai has topped Chinese music charts with multiple singles.

    On July 26, KUN released his newest single Young. Within just 20 seconds, it reached a million sales.

    KUN wrote the song to share his understanding of youth. He mixed R&B and electronic beats (节拍) to make it more cheerful. A reviewer wrote on QQ Music, "When you listen to the song, you just seem to go back to youth again."

    The song was an early birthday present to himself which he celebrated on Aug 2. KUN also hopes that he always has the courage to pursue (追求) his love of music, no matter what people think. "My works are like my children and I have put my best effort into them." he told the Global Times.

    Indeed, KUN has written and produced most of his songs on his own. "I want every piece of my work to have my own spirit in it," he told music website Soundigest, "I feel more enjoyment when I'm performing my own work."

    Although KUN loves performing onstage, when the lights go down, he prefers to fall back into his own world and darkness at night. "I always get inspired when it's quiet, late at night/' he told I-D magazine, "It's a great moment for me to create new things. Sometimes, I can write songs with a melody (旋律) I heard in a dream."

    To develop his introspection (反思) and find new inspiration, KUN attends different kinds of musical performances — from festivals to opera houses. "I just like to do everything, all for my music, all for my art," he told I-D.

    With such talent and dedication to music, it seems that KUN will continue to make his mark in the competitive Chinese music industry.
