1 . What is talent? Are you born with it? Or does it seem to develop over time? Before I start, I’d like to say that one thing everyone agrees on is that the most skilled musicians have worked hard to get there.

While it’s true that a few of us had enough “talent” to avoid extra practice to do just as well as those who did, those who worked hard easily beat us. It is, in fact, very likely that if some of us “talented ones” had actually been practicing and improving our skill, we would have achieved a whole different level.

Another aspect of talent seems to be heart and passion (酷爱). The people I see who are the most talented musicians are crazy about music. They eat, breathe, and live music and they make an extraordinary effort to make it part of their lives. As Remus Badea said, desire for the musician-to-be is significant for them to be successful. This desire is easily found in those considered to be talented. When you want and love something so bad, it drives you and your entire character can be shaped around it. Such determined passion seems to produce incredible skill and talent.

The third aspect (方面) of talent is having talent around you. When surrounded by talented musicians, it only seems natural that you start to catch up to their level Take a look at almost any group of musicians in history. The more talented people in the group the more talented the group is as a whole. A great example of this is the relationship between audio producer and artist. The artist turns up to the studio with their song, and as they work through recording it, the audio producer will often suggest various changes to the song to make it better.

2 . The use of AI (artificial intelligence) is becoming more common in many branches of industry and online shopping. Traditional lines of work, such as goods transport and driving, are developing in a similar direction although mainly out of public view. Scientists at the University of Göttingen have now investigated how efficient (高效的) the use of AI can be in the commercial management of trucks.

“Digital applications—as well as machine leaning, a kind of AI—are increasingly applied to operations and courses in the transport area,” explains Professor Matthias Klumpp from the Faculty of Economics. “The question in the commercial area, however, is whether or not this contributes to achieving goals.”

To answer this question, the researchers compared the work efficiency of truck drivers with their main use of AI applications. Looking at trade delivery by truck, they studied three groups: the first drove completely following human decision-making models; the second used a combination of human and machine; and the third depended completely on fully automated decisions.

The researchers found that an intelligent combination of human work and decision-making abilities with AI applications promises the highest transport and driving efficiency. “On average, the second group achieved the most efficient transport trips, with the fewest interventions (干预) and off-course from the best path.” one researcher said, “Clearly, neither a completely human decision-making structure nor a fully automated driving system can promise to meet current goods transport requirements.” The scientists therefore summarized that despite the progress of AI in the field of transportation by truck, human experience and decision-making abilities will still be necessary in the longer term. However, the challenge is that a wide range of training and qualification (资格) needs will come along by working with Al applications, especially for simple goods transport activities.

3 . With the social media freely available, I've realized how easy it is to become a jealous cow. The truth is that however much I remind myself of the many wonderful things I have in my life, there are still moments when I look at those around me and feel bitterly upset by their success.

It's a horrible thing to admit! In an ideal world, I'd never want to be jealous of another person's achievements and I'd want to celebrate the successes of my friends. But sometimes it's hard, even when we want to. But I don't want to live my life as a jealous cow, and I assume you don't either.

It's easier to celebrate other people's wins if you celebrate your own. How often do we take the time to enjoy our success rather than instantly move onto the next thing we want to achieve? Last year, I decided to write a book. It was the only professional goal I set for myself and, while it tired me out, I got there. But as soon as it was done, I started planning my next goal-making the book a success. As I saw other people publishing books, I stopped celebrating and instead began to fear that mine wouldn't compete.

When I told a friend how I was feeling, she reminded me how much easier it is to clap for someone else when we also clap for ourselves. So, I took myself out for lunch, ordered a glass of wine and wrote myself a congratulations card. When I saw all those other books being written on my social media, I felt proud of each and every one of us who had battled to the end of the word count.

The other trick for celebrating other people's success is to realize that there is no limit on success. We can make more, which means that while it might seem as if others have everything and we have nothing, the reality is that life turns quickly and our luck could change at any time. If others have achieved those things, we can too. When we celebrate others, we're acknowledging their achievements but also cheering for ourselves as well as for our hopes and dreams and our belief that we can make them happen. And hopefully, when we do, those people will cheer for us too.

4 . The joy of giving is real, according to a study. Research presented in the Journal of the Association for Psychological Science shows that those who give gifts are happier — and happier for longer — than those who receive gifts.

Researchers conducted two studies last year. In one，participants were given $5 every day for five days and were required to spend the money on the same thing each day. Some participants were required to spend the money on themselves, while others were required to give to make a donation to charity. In a second experiment that was done online, participants played 10 rounds of a word puzzle game and each won 5 cents per round, which they could keep or donate.

In both experiments, participants reported their overall happiness. Those who donated their money showed that their happiness declined at a much slower rate than those who kept the money or spent it on themselves.

The researchers note that when people focus on an outcome, they can easily compare outcomes, which may diminish their sensitivity to each experience. When people focus on an action, they may focus less on comparison and instead experience each act of giving as a unique happiness-inducing event. Further analyses ruled out some potential alternative explanations, such as the possibility that participants who gave to others had to think longer and harder about what to give, which could promote higher happiness.

The results are especially interesting because according to one of the researchers, Ed O’Brien of the University of Chicago Booth School of Business, they conflict with past research. “If you want to sustain happiness over time, past research tells us that we need to take a break from what were currently consuming and experience something new. Our research reveals that the kind of thing may matter more than assumed: Repeated giving, even in identical ways to identical other，may continue to feel relatively fresh and relatively pleasurable the more we do it,” O’Brien said.

So for all the holiday gifts you give this season, expect to feel happy and know that feeling is going to stick around for a while.

5 . The world has seen many inventions. While most people are proud of those associate with their names, there are things making inventors feel the other way.

The pop-up (弹出) advert, by Ethan Zuckerman

Pop-up ads are convenient for those who are interested, but most people get annoyed when they are on computers. They may contain computer viruses. Just as we would blame the inventor, the man humbly accepted his invention isn’t one of the best. In his essay, Zuckerman wrote about the most hateful thing, “I wrote the code to launch the window and run an ad in it.”

The emoticon, by Scott E. Fahlman

Emoticons began to occupy screens crazily in 2011 and gained great popularity, especially with young men. It had been four years since Fahlman first used a “smiley face” in a computer message. He created the emoticon as a joke marker. But things are different. “It has gone to places I don’t approve of,” he complained to The Wall Street Journal in 2013. “It shouldn’t have been created.”

The office cubicle (隔间), by Bob Propst

In 1968, Bob Propst came up with the idea office cubicles, something that “would build a futuristic and tidy office style with no real walls or doors and provide a more comfortable environment”. But the man has come to hate what he has invented, as Propst recalled to Fortune at age 80, “They’ve changed and just become cubicles”.

The K-Cup, by John Sylvan

It seems everyone has a Keurig coffee maker for K-Cups. John Sylvan invented the K-Cup, aimed at facilitating office life of white-collar workers. Now it’s common in houses and companies. However, the single-serve plastic coffee cups aren’t eco-friendly. “I feel bad sometimes that I ever did it”, Sylvan admits. But! Good news for Mr. Sylvan: Keuring now offers varieties of recyclable K-Cups.

7 . Experts are warning about the risks of extremely picky(挑剔的)eating after a teenager living on a diet of chips and crisps developed lasting sight loss. Eye doctors in Bristol cared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”

The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to the Bristol Eye Hospital because of progressive sight loss.

He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it really arduous to read, watch TV or recognize faces.”

Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too many certain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”
