You may not  have heard of Ashoka,  but for the past 27 years,this association, founded by Bill Drayton, has fought  poverty (贫穷)and sickness, promoted education and  encouraged small businesses. To support these worthy causes, Ashoka provides money for the world's most  promising "changemakers" seeking to solve (解决) urgent problems and would like to create a  world in which every citizen is a changemaker.

    Drayton believes that anyone can become an agent for change. The important thing is to simply give yourself permission. If you see a problem that you care about, you can help solve it. The young in particular are willing to accept this concept because at heart every child wants to grow into a happy, healthy,  contributing adult. In fact It is many young people's ambition to set up programmes or businesses that improve social conditions. An excellent example is an Ashoka project started in 1995 in Dhaka, which handled the rubbish problem facing the city ,helped local farmers and provided an income for poor people there .

When Masqsood and Iftekhar began to study the problem of all the uncollected rubbish that lay in Dhaka's streets, Attracting tats and disease , they discovered that 80% of it was natural waste . So they educated the poor people in the city to compost (把……制成堆粪)this waste . They knew that they would have a market for the end product because local farmers were struggling with chemical ferntilisers (化肥) which were expensive and had reduced the natural minerals in the soil over the years . At first , they were refused ,but once they were able to persuade them that there was money to be made , the project took off. In 2009 sales were $14,000.

    Drayton is optimistic that in ten years Ashoka will be making really serious ,practical progress in bringing about social change by changing the way we look at economic development.

    Dodder is an unusual and unwanted plant that attacks other plants. Except for its flowers, the plant looks like spaghetti, a kind of noodles in the shape of long thin pieces that look like string when they are cooked. It's almost leafless, thread-like stems hang down on top of other plants that dodder needs to stay alive. Dodder does not produce its own food. Instead, it steals food from other plants. It feeds by sucking juices from the plant which is wrapped around, often making its host very weak or even killing it.

    Dodder can find other plants by their smell. When a young dodder plant starts growing, it follows the smell of plants it prefers, like tomato plants, potato plants, or other farm crops. Unlike most plants that usually grow in the direction of light or warmth, a dodder plant will grow in the direction of, for example, tomato smell—if a tomato happens to be growing nearby.

    However, a young dodder plant must find a host plant quickly. It no longer needs its root once it is attached to the host and wrapped around it. If it cannot catch a smell of a potential host within a few days, it will dry up and vanish even if there is plenty of water around. Once it finds a host, the young dodder plant will attach itself to it and start growing faster. At that point the dodder plant will drop its root.

    Dodder is thus a difficult weed to manage and a real headache for farmers. When it does get out of hand, dodder can greatly reduce a farmer's harvest or even destroy crops completely. Before sowing their produce, especially farmers in warm parts of the world often check to make sure no unwanted dodder seeds have mixed with their crop seeds. This is a good way to stop dodder plants from making their way to a crop field secretly.

    We know that hugs make us feel easy inside. And this feeling could actually ward off stress and protect the immune (免疫) system,  according to a new research from Carnegie Mellon University.

    It's a well-known fact that stress can weaken the immune system. In this study, the researchers sought to determine whether hugs could protect individuals from the increased sensitivity to illness brought on by the particular stress that comes with interpersonal conflict.

    "We know that people experiencing ongoing conflicts with others are less able to fight off cold viruses. We also know that people who report having social support are partly protected from the effects of stress on psychological states, such as depression and anxiety," the study's lead author, psychologist Dr. Sheldon Cohen , said in a statement. "We have tested whether awareness of social support is equally effective in protecting us from sensitivity to infection caused by stress and also whether receiving hugs might partially account for those feelings of support and thus protect a person against infection."

    In the experiment, over 400 healthy adults filled out a questionnaire about their perceived (感知到的) social support and also participated in a nightly phone interview for two weeks. They were asked about the frequency that they engaged in interpersonal conflict and received hugs that day.

    Then, the researchers exposed the participants to a common cold virus, and monitored them to assess signs of infection. They found that both perceived social support and more frequent hugs reduced the risk of infection associated with experiencing interpersonal conflict. Regardless of whether or not they experienced social conflicts, infected participants with greater perceived social support and more frequent hugs had less severe illness symptoms.

    "This suggests that being hugged by a trusted person may act as an effective means of conveying support and that increasing the frequency of hugs might be an effective means of reducing the effects of stress," Cohen said. "The apparent protective effect of hugs may result from the physical contact itself or hugging being a behavioral indicator of support and closeness. Either way, those who receive more hugs are somewhat more protected from infection."

    If you need any more reason to wrap your arms around someone special, consider this: hugs also lower blood pressure, reduce fears, improve heart health and decrease feelings of loneliness.

    You are a member in a full-time school called "life". Each day here you will have the opportunity to learn lessons. You may like the lessons or hate them, but you have designed them as part of your curriculum.

    Why are you here? What is your purpose? Humans have sought to discover the meaning of life for a very long time. What we and our ancestors have to overlook is that there is no one answer. The meaning of life is different for every individual.

    Each person has his own purpose and distinct path, unique and separate from anyone else's. As you are traveling your life path, you will be presented with numerous lessons you will need to learn in order to achieve that purpose. The lessons you are presented with are specific to you; learning these lessons is the key to discovering and achieving the meaning of your own life.

    As you are traveling through your lifetime, you may meet challenging lessons that others don't have to face, while others spend years struggling with challenges that you don't need to deal with. You may never know why you are blessed with a wonderful marriage, while your friends suffer painful divorces, just as you cannot be sure why you struggle financially while your peers enjoy abundance. The only thing you can count on is that you will be presented with all the lessons that you specifically need to learn.

    The challenge, therefore, is to arrange yourself with your own unique path by learning individual lessons. This is one of the most difficult challenges you will face in your lifetime, as sometimes your path will be different from others. But don't compare your path with that of people around you and focus on the differences between their lessons and yours. You need to remember that you will only face lessons that you can learn and are specific to your own growth.

    Our sense of fairness is the expectation of equality. Life is not, in fact, fair, and you may indeed have a more difficult life path than others around you, deserved or not. Everyone's circumstances are unique, and everyone needs to handle his or her own circumstances differently.

    It seems we're always being told to get more sleep. Studies suggest spending less time on sleep can lead to obesity(肥胖) and even cancer. You might even find yourself with a head full of false memories. But rarely does science explore the dark side of sleeping too much. That's because few of us in today's busy world have the luck of exploring that option.

    In an August 2018 study, published in the Journal of the American Heart Association, researchers researched the sleep patterns of those "fortunate" few and found they may not be so lucky after all. In fact, they found people who get more than eight hours of sleep have greater health risk compared to those who sleep together less than seven hours. What's more, sleep-aholics-those who manage to get 10 hours a night-stand a 30 percent higher chance of dying compared to the seven-hour crowd.

    The wide-ranging global study involved(涉及) more than three million people who self-reported on their sleep habits and came to an eye-opening conclusion: If you tend to sleep a lot, you may want to buy an alarm clock. As with all things in life, sleep is best taken in moderation(适度).

    You may be thinking: What if I only sleep in on Saturday and Sunday, am I still at risk? The answer is yes, according to a 2019 study published in Current Biology.  Researchers discovered that even if a person sleeps more than seven hours on the weekends but still sleeps less than that on weeknights, they are at risk of gaining weight and developing sensitivity to insulin, which controls the level of sugar in blood.

    For the study, 36 participants were divided into three groups that each had a different sleep schedule: nine hours every night, five hours every night, and five hours from Monday to Friday and sleeping much on weekends. People who get too much sleep tend to feel tired and lack energy. Also, both sleep-deprived(睡眠不足的) groups consume more food and gain weight.

Andy Kong has worked very hard to get to where he is today. He credits becoming a millionaire by 20 to his strict Asian parents who tutored him at a young age by working for the family.

Kong, of Danville, Virginia, started working when he was only nine. English wasn't a strong suit for Andy's parents, and that's where he was able to assist his family the most. After school and on weekends he would help out at their family-owned restaurant and nail salons. Not only did he do the labor work, but he was also involved in creating online ads. This was his introduction to the world of online business.

Andy started his Amazon business in the eighth grade. When he learned about Amazon Dropshipping (代发货模式) from a kid he saw on Instagram, he got inspired and decided to give it a try. Unfortunately, the store eventually got shut down because he was impatient with the growth. Instead of considering it a failure, he viewed this experience as a life lesson and learned from his mistakes. Meanwhile, his parents never stopped trying to talk him into focusing on school and their retail business.

"The biggest challenge when starting a business is getting someone to believe in you," Andy says. He pushed through and did things for himself even when his loved ones discouraged it.

In 2019, Andy met his now business partners, and together, they created an Amazon management company called Project WiFi. This Project has proven to be extremely successful. They currently help over 55 clients run their online businesses, and plan to help many more in the future.

When asked about the secret to his success, Andy says, "Learning to sacrifice whether that's family, friends, or soccer game for a single goal is the only way to succeed, rather than attempting multiple things. If it's worth doing then it's worth doing well with no shortcuts."
