When asked about happiness, we usually think of something extraordinary, an absolute delight, which seems to get rarer the older we get.

    For kids, happiness has a magical quality. Their delight at winning a race or getting a new bike is unreserved (毫无掩饰的).

    In the teenage years the concept of happiness changes. Suddenly it's conditional on such things as excitement, love and popularity. I can still recall the excitement of being invited to dance with the most attractive boy at the school party.

    In adulthood the things that bring deep joy—love, marriage, birth—also bring responsibility and the risk of loss. For adults, happiness is complicated.

    My definition of happiness is “the capacity for enjoyment”. The more we can enjoy what we have, the happier we are. It's easy to overlook the pleasure we get from the company of friends, the freedom to live where we please, and even good health.

    I experienced my little moments of pleasure yesterday. First I was overjoyed when I shut the last lunch-box and had the house to myself. Then I spent an uninterrupted morning writing, which I love. When the kids and my husband came home, I enjoyed their noise after the quiet of the day.

    Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work. I don't think that my grandmother, who raised 14 children, had much of either. She did have a network of close friends and family, and maybe this is what satisfied her.

    We, however, with so many choices and such pressure to succeed in every area, have turned happiness into one more thing we've got to have. We're so self-conscious about our “right” to it that it's making us miserable. So we chase it and equal it with wealth and success, without noticing that the people who have those things aren't necessarily happier.

    Happiness isn't about what happens to us—it's about how we see what happens to us. It's the skillful way of finding a positive for every negative. It's not wishing for what we don't have, but enjoying what we do possess.

    March 8 marks the annual International Women's Day. Around the world, women usually played a not well-known role in history. They were often buried with their unknown talents and amazing tales. Yet there are still some lucky ones whose stories have been recorded. Here are six talented ancient Chinese women who once impressed in their time, and still affect us in our time.

    Praised as the “No.1 talented woman”, Li Qingzhao, a poet from the Song Dynasty, was born in Shandong province. She excelled at poetry and in ink painting and calligraphy (书法). Li was most well-known for her poems, which were divided into two contrasting styles reflecting her life as a married woman and a widow. Before her husband's death, her poems were mainly about a carefree and happy life. The keynote turned into a sad tune after her husband passed away. However, Li was not a narrow-minded woman. Apart from expressing feminine (女性的) feelings and experiences, she also wrote poems praising war heroes and criticizing the corrupted emperor. As an example of female patriot, Li has a great effect on modern women's literature.

    Cai Wenji was good not only at poetry and calligraphy, but also mathematics, astronomy, debate and music. Her masterpieces were Hu Jia Shi Ba Pai. As the daughter of literatus Cai Yi of the Eastern Han Dynasty, Cai had a very unusual life. After her first husband died, she was forced to marry Xiongnu tribe's king. Living in a totally different environment, Cai was very homesick. Twelve years later, Cao Cao, a student of Cai Yi, rescued Cai from the Xiongnu tribe. At the age of 35, Cai got married for a third time in a union arranged by Cao to a man named Dong Si.

    Ban Zhao was the first female historian in China. She was also good at writing poems, yet only seven of her works have survived. Ban was often invited by the emperor to teach the queen mathematics, astronomy and poetry. She was honored as Da Gu, a title for knowledgeable and noble women. At the age of 40, Ban finished Han Shu, based on her brother's writings. A total of four people wrote the book, and Ban, as the last writer, faithfully kept the style of the first three. Ban Zhao also wrote Nv Jie, a book to teach women how to deal with relationships with their husbands and husbands' relatives and how to properly behave.

    Shangguan Wan'er was famous for being given an important position by the only female emperor, Wu Zetian of the Tang Dynasty. Despite Shangguan's grandfather being killed for offending Wu, she was highly praised by the female emperor for her literary talent. She served as a key secretary to Wu and was called “a female prime minister” at the time. Shangguan changed court poetry so that it used more meaningful expressions than empty praise, and further developed her style based on her grandfather's poems.

    Su Hui was known for a handkerchief she made. It was embroidered (刺绣) with 841 characters that could form 7,958 poems. Named Xuan Ji Tu, the handkerchief was originally made by Su to send to her husband, Dou Tao. Su waited for her husband to come back after Dou's exile (流放), yet Dou had an affair with another woman. Sad and angry, Su created the poems on a handkerchief in red, yellow, blue, white, black and purple silk thread and sent it to her husband. Dou was deeply moved by the poems, felt guilty for his behavior and reunited with Su.

    When Xue Tao's name was mentioned, people would think of the famous Xue Tao Jian, a sort of small-size colorful writing paper. It is recorded that Xue Tao created this colored paper to write poems. During her time, writing paper was yellow, yet Xue changed the simple color into different shades of red or green. Later, people made similar colorful paper and named them “Xue Tao Jian”. Xue had talent for poetry and music. Her poems were not limited to those private feminine feelings and emotions; she also expressed her empathy (共鸣) to soldiers on the frontier.

    A 12 -year-old girl who had a feeling that she might be quite clever has taken a test and proved she was absolutely right.

    After raising the idea with her parents and pestering (纠缠)them for the best part of a year, Lydia took the test in her summer holidays. It turns out the test wasn't that hard after all.

    "I was really nervous before the test and I thought it was going to be really hard. But as I started the test, I thought it was a bit easier than I thought it was going to be," she said.

    Lydia Sebastian achieved the top score of 162 on Mensa's Cattell III B paper, showing she has a higher IQ than well-known geniuses Albert Einstein and Stephen Hawking. The comparison doesn't sit well with the British student, who's currently in Year 8 at a selective girl's grammar school in Essex, England.

    "I don't think I can be compared to such great intellectuals as Albert Einstein and Stephen Hawking. They've achieved so much. I don't think it's right," Lydia told CNN.

To explain Lydia's mark's level, the top adult score in the Cattell III B test, which mainly tests verbal(语言) reasoning, is 161. A top 2% score—which allows entry to Mensa, the club for those with high IQs—would be 148 or over. Lydia scored 162, placing her in the top 1% of the population.

    Lydia's not quite sure what she wants to do when she leaves school, although she's leaning toward something "based around Maths, because it's one of my favorite subjects." "All I'm going to do is work as hard as I can, and see where that gets me," she said.

    Humans' invention of zero was vital for modern mathematics and science, but we're not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.

    Honey bees are known to have some numerical skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting food.

    Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren't just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.

    In further experiments, the researchers showed that bees' understanding of zero was even more complex: for example, they were able to distinguish between one and zero-a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators（捕食者）and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.

Dear Coach,

    I have been out of work for almost six months now and things are starting to get very tough for me. I am practically living out of my savings. I have been looking for a job, but things are really bad and I cannot find a single person who wants to hire me. I know that the main problem is that I do not have a degree. I want to go back to school and get my degree, but I also need a job now. I owe money to some people who have been helping me. Because I am out of work, I cannot pay them back. What do you think I should do? I need to find a job as quickly as possible, and want to know what else to do to get people to give me a chance to work for them.

The Unemployed

Dear Unemployed,

    Before you get yourself in a really bad situation, you need to stop borrowing money from people. If you continue doing that, you will be deep in debts and the situation will get even worse for you. The next thing you need to do is look for a job depending on your abilities, skills, and experience. By doing that, you will be increasing your chances of finding a job that suits you best. And the last thing I will suggest is that you should stop feeling sorry for yourself and continue working hard to get a job that you need. Borrowing money, complaining, and feeling bad for your situation will do no good to you. Stay strong and get out there and start showing the world what you can offer. I promise if you work hard and never give up, you will soon find the job that you are looking for. And while you are doing it, thing about getting your degree as well because it will help you to become more challenging. Try those tips.

It was not until photographer Rita Nannini left New York that she grew fascinated by the city's subways. While living in Manhattan for some 15 years in the 1980s and early 1990s, Nannini only commuted (通勤) on the one train-given the subway system's bad reputation. But after relocating to New Jersey for several years where subway is not an option, Nannini found that absence did make the heart grow fonder — maybe even for pizza rats. During her visit back to New York, Nannini nodded, noticing improvements in the subway's facilities.

While Nannini was waiting for a train, a bench on the platform opposite caught her attention due to the ever changing faces and characters. They were people of different accents, colors and beliefs. They were from all walks of life, a diverse mix of New Yorkers all there for their own different reasons. Having learned the teenagers' popular "End of the Line" challenge — boarding trains at random and riding them until their final destination; Nannini decided to visit every first and last stop across the NY subway's lines with her beloved camera.

Nannini's "End of the Line" experience saw her traveling some 665 miles across 26 routes in New York city. She took over 8,000 photos of the final stations, as well as the communities they served. In many cases, she rode the routes two or three times over to ensure she got "the shot". "The project really shows me how important the subway is, and how sustainable it makes our lives," she said 

"It's often said that my photos show the end of the lines — the last stops," she said. "But theend of the line is indeed the start for so many people. That made me think about who the people and the communities that live at the two ends are and what it is that the subway means to them."

Nannini was proud of her set of images directly challenging the traditions of story telling, which echoed both the boredom and excitement of travel on tracks.

Nannini enjoyed taking her time, starting her challenge in 2013 and only shooting the final photos last year. Her first monograph on the terminal stops of the NY subway was released in April 2023.

"When you drive in the suburbs, you don't have those encounters," she continued. "People enter your life on the subway. That's what strikes me most on my jouney on tracks."
