While the U.S. is still debating about getting rid of the penny, Sweden is rapidly moving towards abolishing (to end) currency altogether. Though this may sound radical (过激的), it is a natural evolution in this digital society.

    Sweden, which was the first European country to introduce banknotes in 1661, has just been working harder to convince its residents that digital payments are a safer alternative to carrying cash.

    Over the years, the idea has gained popularity with residents, especially the younger generation that is much more comfortable with technology. Today many banks don't even have ATMs and some have stopped handling cash altogether!

    Tickets to ride public buses in most Swedish cities can only be bought via cell phones. Numerous businesses are also moving towards accepting only digital payments. Even the homeless that sell street paper to make ends meet have to start accepting this mode of payment!

    But despite its growing popularity, some people don't like this radical idea. They include the homeless, elderly people as well as those living in rural areas who are still uncomfortable with mobile phones and computers. But the officials are confident that in the very near future, they will be able to convince everyone to move this safe and more cost-effective payment system.

    Sweden is not the only country trying to abolish paper currency and coins. The movement is rapidly gaining ground in Denmark and Finland as well. In 2014，Israel announced a three-step plan to go cashless and just last week the vendors (小贩) of a popular street in Sydney declared they would stop accepting currency from customers. Whether this phenomenon spreads remains to be seen. But one thing is for sure-With increasingly advanced payment systems being introduced every day, pulling out cash is rapidly becoming “uncool”.

    Before we came to Canada in 1951, when I was three, my parents and I spent a year at refugee camp (难民营) in Austria. We had escaped from what was then called Czechoslovakia. My parents had already lost their livelihood once to the Nazi. Mummy was freed from the Nazi concentration camp Bergen-Belsen and spent the years after the war trying to find her family, only to discover she was the only survivor. She met my father in a small town outside Prague. They married and had me in 1948. When we arrived in Montreal, everything we owned was contained in an army trunk and a couple of army blankets. Mummy bought an old sewing machine and some inexpensive materials and using patterns in magazines, taught herself to sew. Her hands were always going, making something. She learned English by singing along to the hit song as she worked.

    For me, high school was a lonely time. My mother worried that I'd never come out of my shell so she signed me up for classes at the Montreal Children's Theatre. That's where I found my voice with her strong faith in me, Mummy had opened a door. Although she was an educated woman, I never heard my mother said “This is what I gave up for you.” She was always there for my younger brother and me. When I sat in the kitchen with her, I felt safe. When she made soup or sewed a ballet costume for me, it was all a gift, a labor of love. She wanted to make us happy. For a long time, I had a picture hanging in the kitchen saying “Put your heart into it.” I grew up with that phrase. Mummy taught that lesson by example, and it has become my own work ethic(职业道德).

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

    Fellow Robots is one company bringing social robots to the market. The company's "Oshbot" robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. "We have technologies to train social robots to do things not for us, but with us," said Breazeal.

    She was returning from teaching out in a small community. It was a black, moonless night, and a heavy snow was falling.

    She thought back to the time when she had first started teaching out in small communities. During those days she had always picked up hitchhikers (搭便车者), until the day her sister told her that one of her friends had been shot in the head by a hitchhiker, all because she had stopped out of kindness to help him during a storm.

    Her family didn't stop worrying about her safety over the hitchhikers until the family heard the promise: “No more hitchhikers!” The snow that night was making her think back to this.

    Then she saw a man waving. She slowed down for him, but as he ran toward the car in the dark, she shook with fear. Yet she thought that if he was truly in need, she couldn't leave him here in this storm.

    The stranger explained that his car was dead, and she told him to get in. They drove for an hour into the next city and she took him to a convenience store. She waited until he had made a call. When he reported back to her that a family member would soon come to pick him up, she wished him well and then left.

    Tears fell on her cheeks as she drove away. It felt as though she had been holding her breath for an hour.

    “I hope they'll understand why I had to break my promise,” she thought.

    Five-year-old Prisilla Perez, a student at Meador Elementary School in Willis, was unhappy with her recent haircut, which resulted from a severe disease. When students in her class started calling Prisilla a boy, she felt ashamed, often crying and losing focus in school.

    Her teacher, Shannon Grimm, sympathized with her unhappiness. Grimm and Prisilla's mom were concerned, but their ideas didn't work. “We had classroom discussions about how girls have short hair and boys have long hair, and I showed them photos of movie stars with different looks,” Grimm said. “However, it wasn't sinking in.”

Grimm thought about Prisilla throughout winter break, and one morning, she had an idea: Cut off her hair — a scary thought for Grimm, who wore her hair long and took pride in it. “I've never had short hair, and I stressed about it for two weeks before making a decision,” she said. On Jan. 4, Grimm invited a hairstylist friend to her home. “I told him to keep going, even if I cried,” she said.

    The class loved their teacher's new do, especially Prisilla, who excitedly ran off the school bus that afternoon yelling, “Mom, Ms. Grimm cut her hair!” The teacher also bought matching bows for herself and the girl, so they could style their hair together.

    In February, the teacher recommended Prisilla for the school district's Student of the Month Award, but during the Monday ceremony, she received a surprise “hero medal” from the girl. “Now we have matching awards,” says Grimm.

Prisilla's mother, Maria, said that Grimm's thoughtfulness brought her to tears. “I was shocked. I was crying. I couldn't believe it — she did something I wouldn't have the bravery to do. I will never forget that.”

    Don't put it off, do it now!

    Why do we spend so much time not doing the work we should do, or putting off small jobs that have piled up to create a big problem? Procrastinating, as putting things off like this is called, is in our character we have naturally since birth; we avoid dull or difficult jobs until it's too late to do anything else.

    "We often put things off although we know it will make life more stressful," says Dr. Steel, an authority on the science of motivation. "If these tasks were fun, we'd just do them now. We put off what is difficult or unpleasant, such as the paperwork that needs doing before leaving the office or cleaning the bits of your home that people can't see. But the fact is, the less people procrastinate, the more money they have, the better relationships they have, and the healthier they are." This is obvious when you look at the couples who don't argue about whether anyone has cleaned the kitchen, and the people who simply go for a run instead of endlessly rescheduling it in their heads.

    Of course, there are the rest of us, who feel the small jobs piling up around us daily. "We've evolved to respond to the moment, and not to set our sights too far in an uncertain world," Dr. Steel adds. "We are not set up to appreciate long-term rewards, whether it's the benefit of a four-year degree, doing exercise or dieting. We usually feel the cost now and the reward comes much later." According to Dr. Steel, we have two decision-making systems. They are the limbic, which is responsible for the short term, and the prefrontal cortex, which deals with the future. We bounce between long-term goals and short-term temptations, so we need goals that will translate our plans for the limbic system.

    Let's take the example of students' writing essays. They should set themselves targets and word counts per day. These are thus turned from seemingly endless tasks into something concrete with measured progress. Dr. Steel recommends such techniques, or "pre-commitments", adding that leaving you a month before the "deadline" makes it more likely a task will be completed. The benefit is that you'll avoid the embarrassment of not following up on something people are expecting you to do—telling everyone you are going to take up jogging makes you more likely to do so.

    Overcoming procrastination finally comes down to planning, which, if you're not careful, becomes procrastination in itself. But it is worth making sure you have everything in place. "Successful people don't pretend they don't procrastinate," Dr. Steel says. "People who pretend they have willpower are less successful." Instead, plan for procrastination: make your work environment a temple of productivity by cutting out what stops you paying your attention, so you can really focus on moving forward.
