Raeann Sleith began making bracelets (手链) when she was six. Family and friends loved her designs and asked for more. When admirers suggested that Raeann sell her bracelets, she realized she wanted to do just that — and donate the money to help kids with special needs, like her brother Derek.

    Raeann's older brother, Derek, has cri du chat syndrome. Children with cri du chat usually have problems understanding ideas and might have a hard time learning to talk. Many also have weak muscles that can cause problems with walking or using their fingers to pick things up. The term cri du chat means “cry of the cat” in French. Babies with cri du chat often have a high-pitched cry that sounds like that of a little cat.

    Over the years, Derek's teachers helped him learn sign language and gestures. They also taught him skills such as recognizing letters, cutting with scissors, and understanding basic math. Raeann wanted to donate money to Derek's school. “I just wanted to help my brother,” she says, “and the people who help him.”

    At first, Raeann focused on creating jewelry that would raise awareness for cri du chat. But people started requesting bracelets to wear as a symbol of support and awareness for a variety of other diseases and disorders. To create those symbols, Raeann researched the color most often associated with raising awareness for the disease or disorder, such as pink for breast cancer or orange for leukemia.

    In the end, it turned out to be a great idea. In only a few years, Raeann has donated more than $30,000 to local charities. Raeann's mom says that working on the bracelets has developed the generosity and kindness that already existed in her daughter. Raeann plans to keep making bracelets and raising dollars for charities. “I just want to keep going on with it,” she says, “to help my brother more.”

    English is full of colorful phrases to describe shyness. Someone shy might be called shrinking violet or a wallflower, while for especially nervous types we have the curious expression: they wouldn't say boo to a goose.

    None of these are traditionally seen as positive descriptions, even if you like geese. In a culture of go-getting, high achievers, shy people don't come first. Or that's what the self-help industry would have you believe. Bookshops are filled with vital tomes(巨著) that promise to help beat social fears and find success in life, love and business. That is why one book, Shrinking Violets: A Field Guide to Shyness, bucks the trend. It became a sudden success across English-language media recently for its new take-on shyness.

    Author Joe Moran says that despite struggling with shyness and longing for loneliness all his life, being shy can also be "a gift". Freed from the constant urge to participate and compete in social situations, people are liberated to look at the world in new ways, and gain fresh insights.

    Indeed, many of the world's great thinkers and artists are introverts(内向的人). Scientists Charles Darwin and Albert Einstein preferred their own company; actress Keira Knightley often finds herself tongue-tied at parties; and Harry Potter author JK Rowling claims she used to be too nervous to even borrow a pen.

    Moran told BBC Future: "I think shyness probably does turn you into an amateur anthropologist(人类学家), really-you are more likely to be an observer."

    So, while extroverts make all the noise, they don't necessarily have the best ideas.

    If you're shy, you've probably known this for a long time. You just don't shout about it.

    Maybe you've heard about the saying, “A bird with a broken wing will never fly as high. I'm sure that T. J. Ware was made to feel this way almost every day in school.

    By high school, T. J. was the most famous troublemaker in his town. He got into lots of fights. He failed almost every exam but was passed on each year to a higher grade level. Teachers didn't want to have him again the following year.

    When I showed up to lead the first training for a leadership retreat, a program designed to have students become more involved in their communities, the community leaders told me about T. J. Ware, the boy with the longest arrest record in the history of town. Somehow, I knew that I wasn't the first to hear about T. J.'s darker side as the first words of introduction.

    At the start of the retreat, T. J, didn't readily join the discussion groups and didn't seem to have much to say. But when his group started a discussion about positive and negative things that had happened at school that year, he joined in and had clear thoughts on those situations, and the other students in his group welcomed his comments. Suddenly, T. J. felt like a part of the group, anti soon he was treated like a leader. He was saying things that made a lot of sense, and everyone was listening. By the end of the retreat he had joined the Homeless Project team. He knew something about poverty, hunger and hopelessness. The other students on the team were impressed (打动) with his ideas and love for the homeless. They elected T. J. vice-chairman of the team.

    Two weeks later, the Homeless Project team organized a communitywide service project—a giant food drive. Seventy students led by T. J. collected a school record: 2,854 cans of food in just two hours, enough to take care of poor families in the area for 75 days. The local newspaper covered the event with a full-page article the next day. T. J.'s picture was up there for doing something great.

    T. J. reminds us that a bird with a broken wing only needs mending. But once it has healed, it can fly higher than the rest.

    An open office is supposed to force employees to cooperate. To have them talk more face to face. To get them off instant messenger (IM) and brainstorming new ideas. But a recent study by two researchers offers evidence to support what many people who work in open offices already know: It doesn't really work that way. The noise causes people to put on headphones and tune out. The lack of privacy causes others to work from home when they can. And the sense of being in a fishbowl means many choose email over a desk-side chat.

    Ethan Bernstein and Stephen Turban, two Harvard Business School professors, studied two Fortune 500 companies that made the shift to an open office environment from one where workers had more privacy. Using “sociometric” electronic badges (徽章) and microphones, as well as data on email and instant messenger use by employees, the researchers found in the first study that after the organization made the move to open-plan offices, workers spent 73% less time in face-to-face interaction. Meanwhile, email use rose 67% and IM use went up 75%.

    The participants wore the badges and microphones for several weeks before the office was redesigned and for several after, and the company gave the researchers access to their electronic communications. The results were astonishing. “We were surprised by the degree to which we found the effect,” Bernstein said. The badges could tell that two people had a face-to-face interaction without recording actual spoken words. The researchers were careful to make sure other factors weren't in question—the business cycle was similar, for instance, and the group of employees were the same.

    In a second study, the researchers looked at the changes in interaction between specific pairs of colleagues, finding a similar drop in face-to-face communication and a smaller but still significant increase in electronic correspondence.

    Another wrinkle in their research, Bernstein said, is that not only did workers shift the way of communication they used, but they also tended to interact with different groups of people online than they did in person. Moving from one kind of communication to another may not be all bad—“maybe email is just more efficient,” he said—but if managers want certain teams of people to be interacting, that may be lost more than they think. The shift in office space could “have strong effects on productivity and the quality of work”.

    Bernstein hopes the research will offer evidence that will help managers consider the possible trade-offs of moving to an open office plan. In seeking a lower cost per square foot, they buy into the idea that it will also lead to more cooperation, even if it's not clear that's true. “I don't blame the architects,” he said. “But I do think we spend more of our time thinking about how to design workplaces based on the observer's angle”—the manager—“rather than the observed.”

    In the kitchen of my mother's houses there has always been a wooden stand (木架)with a small notepad(记事本)and a hole for a pencil.

    I'm looking for paper on which to note down the name of a book I am recommending to my mother. Over forty years since my earliest memories of the kitchen pad and pencil, five houses later, the current paper and pencil look the same as they always did. Surely it can't be the same pencil. The pad is more modern, but the wooden stand is definitely the original one.

    "I'm just amazed you still have the same stand for holding the pad and pencil after all these year." I say to her, walking back into the living-room with a sheet of paper and the pencil. "You still use a pencil. Can't you afford a pen?"

    My mother replies a little sharply. "It works perfectly well. I've always kept the stand in the kitchen. I never knew when I might want to note down an idea, and I was always in the kitchen in those days."

    Immediately I can picture her, hair wild, blue housecoat covered in flour, a wooden spoon in one hand, the pencil in the other, her mouth moving silently. My mother smiles and says, "One day I was cooking and watching baby Pauline, and I had a brilliant thought, but the stand was empty. One of the children must have taken the paper. So I just picked up the breadboard and wrote it all down on the back. It turned out to be a real breakthrough for solving the mathematical problem I was working on."

    This story—which happened before I was born—reminds me how extraordinary my mother was, and is, as a gifted mathematician. I feel embarrassed that I complain about not having enough child-free time to work. Later, when my mother is in the bathroom, I go into her kitchen and turn over the breadboards. Sure enough, on the back of the smallest one, are some penciled marks I recognize as mathematics. Those symbols have traveled unaffected through fifty years, rooted in the soil of a cheap wooden breadboard, invisible(看不到的)exhibits at every meal.

    The world's richest man might seem to have it all, but Bill Gates has one regret. The self-made billionaire said he felt stupid for not knowing any foreign languages.

    Speaking in his third Ask Me Anything question-and-answer session for online forum Reddit(红迪网), the Microsoft founder said that he wished he spoke French, Arabic or Chinese.

    He said, "I took Latin and Greek in high school and got As and I guess it helps my vocabulary. I keep hoping to get time to study one of these—probably French because it is the easiest. I did Duolingo for a while but didn't keep it up."

    Gates, who is worth $79.3 billion, praised Facebook founder Mark Zuckerberg for surprising an audience in Beijing when he spoke fluent Chinese. "Mark Zuckerberg amazingly learned Chinese and did a Q & A with Chinese students—unbelievable, isn't it?" he said.

    This isn't the first time for Gates to admit his regret over language. He also showed his habits at home and personal insights.

    Last February, Gates said he likes to do the dishes himself—to his own special standards every night and also told the interviewer that his wife, Melinda, would likely want Samuel L. Jackson to play her husband in a biopic(传记片).

    He also admitted that he would pick up a $100 bill if he found it on the street.

    As he took the top spot on Forbes(福布斯) 28th Annual Billionaires list last year for the fourth time, he said he is pretty basic when it comes to spending on clothes and food, but that he enjoys investing in shoes and rackets(球拍) when he plays tennis.

    When asked a life lesson he had to learn the hard way, the billionaire said staying up too late is a habit he is still trying to break. "Don't stay up too late even if the book is really exciting. You will regret it in the morning. Pam is still working on this problem," he said.
