We may be only three weeks into December, but artist Jonnie Hartman has been in the holiday spirit for months, designing and building the Grand America Holiday Window Stroll.

The goal with each window stroll is to create playful and uplifting displays (展示), according to Hartman. "I really try to do something lighthearted, something whimsical, that is, something everyone can connect with and maybe not see every day in the real world," Hartman said.

    She designs all of the window displays by hand, starting with pencil sketches, then illustrating the designs on her computer and sending parts of the drawings to be printed. From there, Hartman works with a team of five people to build the displays, creating, sewing and embellishing (润色) many elements by hand.

    However, a challenge Hartman has faced over the years as she has designed the displays is making sure all of the measurements are right for elements to fit inside the windows.

"When I was in college, I was an art major, and I thought, 'I don't need math. I will never use it. I'm an artist,' and guess what, it's the most important thing that I use, ''Hartman said. "If I don't get that right, then the windows don't fit, the pieces don't come together and it just doesn't work out."

    The holiday window stroll gives Hartman a unique opportunity to hear feedback from those who observe her creations, which is something she doesn't always get to experience with her other artworks. She said it's fun to hear people's reactions as they go through the holiday window stroll.

"It just makes me happy that I can kind of set the tone for people's holiday season and just maybe bring a smile to their face," Hartman said.

    A few years ago, my wife, Sue had some serious health problems. She had suffered surgery after surgery and had also put on weight. Diets had not helped her and she suffered constantly from undiagnosed pain. One day the whole family sat down and drew up a “wish list”. To our surprise, one of Sue's items was to run in a marathon. Given her history and physical limitations, I thought her goal was completely unrealistic, but Sue became committed to it.

    She began by running very slowly and every day she ran just a little farther than she did the day before. Soon she could run three miles. Then five. Sue kept practicing and longed to run in the St. George Marathon in southern Utah.

    On the big day, I parked our van near the finish line, waiting for Sue. The rain was steady and the wind was cold. The marathon had started over five hours ago. The fast and strong competitors had finished already. Several cold and injured runners had been transported past me, and I began to panic. The image of Sue, alone and cold, off the road somewhere, made me sick with worry.

    Another hour passed and I spotted a small group running up. As they approached, I could see Sue, in the company of three others, and a woman in her twenties was near Sue. It was obvious that they had become friends during the race. I could see her begin to struggle. But when the finish line came into sight, she confidently even happily picked up her pace the last hundred yards to the finish line. Few people were left to congratulate my wife. They openly praised and embraced her, “She made us believe we could do it,” her new friend stated.

    From then on, she was carrying herself differently. Her head was more upright. Her shoulders were squared. Her walk had a new confidence. Her voice held a new, quiet dignity. It was not as if she had become someone new; it was more as if she had discovered a real self she had not known before. It was perseverance that made her realize she was an undiscovered masterpiece with a million things left to learn about herself. She truly liked her newly discovered self. So did I.

Be careful on January 8^th — It's officially the most dangerous day of the year. The insurance company Hyperion has studied accident statistics(统计数字) and has found that there are more accidents on January 8^th than on any other day.

    Accidents are certainly more likely to happen at particular times of the year. One general rule is that more accidents happen in winter months, because risk increases in bad weather. In 2004 and 2005 Hyperion found that the worst day was January 8^th, with 298 accidents reported to them. March 3^rd was the safest day, with only 89 reports. Six of the ten worst days for driving were in January.

    It's clear that icy and snowy conditions are dangerous, but some other statistics are puzzling. A British Medical Journal report in 2001, for example, found that hospital admissions(住院) were always higher than usual on Friday the 13^th.

But it is not only when Friday falls on the 13^th that it is a dangerous day. Four of the top ten worst days for accidents last year were Fridays — perhaps because everyone is rushing home for the weekend — while Thursdays are the safest day of the week.

At what time of the day is an accident most likely to happen? The Health and Safety Authority found that people are most likely to have an accident at 11.00 a.m., while the safest time of day is between 4.00 and 5.00 a.m. — probably because most people are in bed!

    Finally, good news for Harry Potter fans. Doctors at the John Radcliffe Hospital in Oxford noted that fewer children were in hospital on the weekend when Harry Potter books were available to the public. Casualties(伤亡人员) fell by over 50% when the last two books went on sale. So if you want to be really safe, you should read a Harry Potter book in bed, at around 5.00 on a Thursday morning, in summer.

    People like to post their selfies(自拍照) on social media. To know more about it, scientists at Syracuse University in New York recently did a research and came up with some surprising findings.

    People who post selfies and use editing software to make themselves look better show behavior connected to narcissism(自恋), the researchers said. Makana Chock, a professor from Syracuse University, said because social media is mostly used by people to share unimportant information about their lives, it is a good place for people to "work towards satisfying their own vanity." Those "likes" under their Facebook selfies make them feel good.

    Besides, people who post group selfies show a need for popularity and a need to belong to a group, the research found. Some people feel "peer(同伴) pressure" to post selfies and some follow the popular belief that if there is no picture of an event or experience, it did not really happen. "Anyway, it shouldn't be seen as negative. People get sense of satisfaction especially when they get likes. And it does no harm," Chock said.

    Other findings from the study include: There are no major differences on how often men and women post selfies and how often they use editing software. But men who post selfies showed more of a need to be seen as popular than women who posted selfies.

Chock said posting selfies on social media is not all that different from what people have done for many years. On trips and special events, our parents and grandparents used cameras instead of phones to take photos. They would bring back photos to show friends and family. You had no choice but to look at them. You probably commented about how nice everyone in the photos looked, especially children and the person showing the photos. They were happy to hear your comments. That was the old way of "clicking like". On social media, however, people can decide not to look at photos — even if they click "like".

Many of us were told from an early age that, "you learn from your mistakes". But is this actually true?

The short answer is "yes" — failure can be a teachable moment. But learning from our mistakes is, in reality, very hard because we don't like to fail. It doesn't feel good, so we react to failure in impulsive and emotional ways, like giving up on a task prematurely, telling ourselves we don't care whether we succeed, or finding fault with the task itself. This is self-protective, according to Hallgeir, a professor of psychology at the Norwegian School of Economics. "Most of us want to think of ourselves as competent", he says, so when we fail "it poses a serious threat to our self-image".

Fortunately, there is research to suggest that there are some strategies to help us overcome the emotional barriers around failure. One of them is to adopt a third-person perspective. Instead of asking "Why did I fail?", we could ask "Why did Sam fail?", for example. Multiple studies by psychologist Ethan Kross at the University of Michigan show that adopting a third-person perspective helps to soften our negative emotional reactions, allowing us to look at failure more objectively.

A second strategy involves offering advice to others who may be in the same position as us. This strategy led to better levels of motivation and academic success in the test groups — involving both adults and children — that were asked to give advice based on their own failures. Professors Eskreis-Winkler and Duckworth found that the satisfaction of helping others "forces people to engage with their experience and what they have learned". 

The writer Samuel Beckett once said: "fail again, fail better". But it now seems that we should be saying: "fail again, fail smarter". Failure is an unavoidable part of life, but by learning to overcome the emotional barriers around it, we may find the road to success is a little easier to navigate (确定方向).

Chinese President Xi Jinping once said. "Heroes come from the people." Every year, there are ordinary people spreading positive energy (正能量) and touching our hearts. Let's take a look at some of them.
