I considered an active social life as basic human necessity. Yet when it dawned on me just how much time I was spending socialising, I realised I may be taking it to an extreme. I calculated that, on average, I was spending 22 hours or more each week on social activities. So, to see what would happen to my work output, health and wellbeing, I decided to try and cut out my social life entirely.

    I knew, at times, I filled my schedule simply out of fear of missing out (FOMO), but also as a way to shift focus away from my work. For one month, I declined all in-person activities with friends: going out for drinks; dinners; parties and non-work related events, to see if it would make me more productive, improve my focus and career prospects.

    On day one of the month-long experiment, I had to fight some anxiety over missing out. But as the days passed, I started to relax. I only had one option to consider for Saturday night—to stay home—and this limitation left me more satisfied in my decision. I felt more content working, reading or watching TV.

    While I found more time to work, I also noticed a change in my overall health. I found myself cooking more at home, doing daily exercise, getting to bed earlier each night, reading, and enjoying moments of rest and boredom throughout the day.

    Having no social life left me more free time than I'd imagine. Such idle moments are vital for creativity, and mind wandering has been linked to creative problem solving. During the experiment I found myself regularly brainstorming new ideas and reimagining existing projects.

    Of course socialising is an important way to build work contacts. While one month of no social life did not impact my relationship with existing clients, if I had continued, it may harm my ability to build new ones.

    Do you still remember your favorite poem from high school or some other important periods in your life？Why is it that decades later it still stands out in your mind？Probably the main reason is that some aspect of that poem resonates (引起共鸣) with you. In the same way, you too as a school leader can touch the hearts of your teachers and students.

    Poetry allows us to experience strong spiritual connections to things around us and to the past. The power that poetry has displayed over time and across cultures actually satisfies this common need of the human heart and soul.

    As one of the oldest art forms, poetry has successfully connected various parts of humanity (人性) from one generation to another. Referring to poetry, Hillyer makes a simple yet meaningful statement, “With this key mankind unlocked his heart.”

    School leaders can find and make use of the value of poetry for themselves, their students and their teachers. Beyond the simple use of poetry, techniques of poetry such as repetitions can be used to take advantage of the power of language to transform communication, create meaning and a culture of care and attention.

    Since schools are mainly about people and relationships, school leaders, like poets, are required to inspire and encourage the human heart. The use of poetry—or even of some techniques of poetry—in school leadership not only helps to improve communication, but also serves to meet the human need for inspiration.

    As more and more schools rush to put digital devices（数码设备）in the hands of every student, many parents are becoming increasingly concerned about the quality of their children's education. The promise of increased student academic（学业上的）achievement through the use of technology hasn't produced any significant results in the past 20 years.

    Researchers at the University of California Los Angeles conducted a study in 2014 to determine if the social skills of elementary students were blocked by screen time. Two groups of sixth grade students were compared. One group was sent to an outdoor camp for one week with no screen time, while the control group live life as normal. After one week, the students at camp had made significant improvements over their peers（同龄人）. The good news is that when we limit access to screen time and give children the opportunity to interact face to face, they quickly become better at reading the emotional state of others. The bad news is that we have a generation of children that struggle with this basic emotional intelligence skill.

    Too much screen time has been linked to childhood obesity, sleep disorders, behavior problems, and academic challenges. But is there a difference between schoolwork and entertainment media?

    When students are using technology for academic work they are more likely to be communicating with peers, working cooperatively, and developing other important skills. However, all these are impossible when students watch entertainment media. They just sit and watch!

    Parents have right to be concerned about their children's screen time at school, but they should begin by discussing the use of digital media at home. Some parents are continuously engaged in their own devices, responding to every ring of their phones, receiving and sending messages. How can they expect their children to do better?

    A project in Gambia is empowering women and reducing dangerous waste at the same time.

    The Waste Innovation Center, funded by the European Union's Global Climate Change Alliance, shows women in the Brikama area how to recycle waste into useful materials and products, which they can then sell in local markets.

    Wood-like waste is recycled into charcoal (木炭), for example, which can be used to supersede firewood and reduce the number of trees that are cut down for firewood. Food waste is recycled into compost(混合肥料)to function as environmentally friendly fertilizers and plastic is turned into many useful things.

    Supported by Waste Aid UK and the Gambia Women's Initiative (GWI), among others, the project provides women with skills they can use to become self-sufficient (自给自足的). Women learning at the center come from five communities, and some of them travel as far as 12 miles to learn these important skills that will provide them with an income, according to The Guardian.

    Isatou Ceesay, who now leads the GWI, highlighted the need to focus on economic equality in her country, telling The Guardian, "In terms of education, women are the ones who are always behind. Boys are chosen to go to school. When we conduct our training, we find women can do a lot, but don't know who they are, or how to carry out things. "

    According to the World Health Organization's Country Cooperation Strategy 2018—2023 report, the main environmental issue facing Gambia is poor waste management in urban areas. Ndey Sireng Bakurin, executive director of the National Environment Agency, has voiced concern over health and environmental risks, such as water pollution, the increase of insects as well as flooding that occur as a result of poor waste management.

    Parents should ban electronic media during mealtimes and after bedtime as part of a comprehensive "family media use plan", according to new recommendations from the American Academy of Pediatrics. "Excessive media use is associated with obesity, poor school performance, aggression and lack of sleep", said Marjorie Hogan, co-author of the new policy.

    Families should have a no-device rule during meals and after bedtime, the guidelines say. Parents should also set family rules covering the use of the Internet, cellphones, including, perhaps, which sites can be visited, and who can be called. The policy also restated the existing recommendations: Kids should limit the amount of screen time for entertainment to less than two hours per day; children younger than 2 shouldn't have any TV or Internet exposure. Also, televisions and Internet-accessible devices should be kept out of kids' bedrooms.

    Doctors say parents need to obey the family rules, too, to model healthy behavior. That, some say, may be the toughest part. "If you go to any restaurant, Family 3.0 is Mom and Dad on their devices and the kids on theirs", says Donald, a pediatrician and an AAP spokesman. "Who is talking to each other?"

    Children aged from 8 to 18 spent an average of 7 hours and 38 minutes a day consuming media for fun, including TV, music, video games and other content in 2009, according to a 2010 report from the Kaiser Family Foundation. The report was based on a survey of 2002 third through twelfth graders, 702 of whom completed a seven-day media use diary. That was up about an hour and 17 minutes a day from five years earlier. About two-thirds of 8 to 18-year-olds said they had no rules on the amount of time they spent watching TV, playing video games or using the computer, the Kaiser report found.

    Use of mobile devices by young kids has soared. A new report from Common Sense Media, a child-advocacy group based in San Francisco, found that 17% of children 8 and younger use mobile devices daily, up from 8% in 2011.

    Andrew Ritchie, inventor of the Brompton folding bicycle, once said that perfect portable bike would be "like a magic carpet... You could fold it up and put it into your pocket or handbag". Then he paused: "But you'll always be limited by the size of the wheels. And so far no one has invented a folding wheel."

It was a rare — indeed unique — occasion when I was able to put Ritchie right. A 19th-century inventor, William Henry James Grout, did in fact design a folding wheel. His bike, predictably named the Grout Portable, had a frame that was divided into two and a larger wheel that could be separated into four pieces. All the bits fitted into Grout's Wonderful Bag, a leather case.

    Grout's aim: to solve the problems of carrying a bike on a train. Now doesn't that sound familiar? Grout intended to find a way of making a bike small enough for train travel: his bike was a huge beast. And importantly, the design of early bicycles gave him an advantage: in Grout's day, tyres were solid, which made the business of dividing a wheel into four separate parts relatively simple. You couldn't do the same with a wheel fitted with a one-piece inflated(充气的) tyre.

    So, in a 21st-century environment, is the idea of the folding wheel dead? It is not. A British design engineer, Duncan Fitzsimons , has developed a wheel that can be folded into something like a slender ellipse(椭圆). From beginning to end, the tyre remains inflated.

    Will the young Fitzsimons's folding wheel make it into production? I have no idea. But his inventiveness shows two things. First, people have been saying for more than a century that bike design has reached its limit, except for gradual advances. It's as silly a concept now as it was 100 years ago: there's plenty still to go for. Second, it is in the field of folding bikes that we are seeing the most interesting inventions. You can buy a folding bike for less than £1,000 that can be knocked down so small that can be carried on a plane ——minus wheels, of course ——as hand baggage.

    Folding wheels would make all manner of things possible. Have we yet got the magic carpet of Andrew Ritchie's imagination? No. But it's progress.
