I have an interest in photography and follow many photography Instagram accounts. Just like me, a friend of mine has a similar interest. The only difference is that he is a traveller and has taken hundreds of beautiful photos. He is really talented.

    Having returned from one trip, he shared some of his latest photos. Blown away by the images, I asked him why he hadn't started his own Instagram account of shots.

    “It's hard to start when there are already so many other websites devoted to travel photography with thousands of followers”, he explained. “What if I don't get any followers or what if people don't like my shots?”

    “Yet how will you ever know if you don't try?” I asked.

    He just shrugged and quickly changed the subject. I knew this feeling well. The feeling of self-doubt.

    That was when I was ten years old. I participated in a guitar competition. My grandfather helped me write a short speech to address the crowd and judges. But as the competition began, doubt consumed me and questions flooded my head. I thought to myself, “If I do say the speech, will the other girls laugh at me? Will the judges think I'm being silly for doing my own talk?”

    Then with a shake in my voice I said, “My name is Heidi Ceci. I live in St. Catharines and I play the guitar.” Nothing more... and nothing less.

    But the next girl walked up to the microphone and actually said a speech. I just stared at her in complete disbelief. No one seemed to be judging her for doing something different. In fact, they applauded louder for her than any other girl.

    From then on, I never let fear and doubt rule my decisions. Whatever happens, I always take chances and have a try.

    Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. Americans won't live without cars!

    Most Americans would find it hard to think what life would look like without cars. However, some have realized the serious problems of the air pollution that is caused by the car.

    The polluted air becomes poisonous and dangerous to health.

    One way to get rid of the polluted air is to build a car that does not pollute. That's what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

    Another way is to take the place of the car engine by something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model that pleases man.

    To prevent the world from being polluted by cars, we'll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help keep the air clean.

    But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down. Thus the problem of air pollution would become less important than that of unemployment.

    Although cars have led us to a better life, they have also brought us new problems.

    On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk, Strayer explained that all this time spent with technology is making our brains tired.

    Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains , is important for critical (有判断力的)thinking , problem-solving and decision-making.

So, it is important to give the brain a rest. And being in naure, Strayer claims, helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore, swim, sleep, eat and play. Camping may be just what a tired brain needs.

    Take Carl for example .He lives in West Virginia and enjoys camping. He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children. She calls it a “regenerative” experience.

    At the University of Utah, David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However, he found, it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

    This year marks the 170th anniversary of Paul Gauguin's birth. He lived for just 54 years but he packed his brief life with activity.

    The French painter spent his early childhood in Peru before returning to France. As an adult, he continued to travel a lot. Most famously, he spent much of the last decade of his life in Tahiti, an island in southern Pacific Ocean. Indeed, Gauguin is best known for his colorful paintings of Tahitians and their culture.

    The restlessness of this great painter has been normal among modern artists since the middle of the 19th century. They're never satisfied for long with a certain style or way of life. Once something becomes conventional, it's turned down.

    The artistic culture that Gauguin developed from was that of Impressionism (印象派). Painters like Claude Monet had wanted to paint how they saw the world, not how their teachers taught them it should be seen. Gauguin, and similar artists like his friend Vincent van Gogh, moved even further away from "respectable" art than the Impressionists. For them, it was not simply a matter of seeing the world differently, but feeling and thinking about it differently, too.

    Gauguin saw, felt and thought differently from most members of European society. He thought that European culture was too fancy and not spontaneous. This is why he turned to the traditions of other parts of the world, like Africa, and, eventually, Tahiti. Artists like Gauguin used the word "primitive" for these cultures, but not as a negative term. For him, Europe, in becoming modem, industrial and scientific, seemed less natural than other parts of the world.

    In truth, Gauguin's paintings may be unconventional but they are certainly not "primitive". They are the work of a painter with great awareness of what he was doing. It was this awareness that made him such an important painter for those that came after, in the 20th century. When we look closely at the works of Gauguin we begin to understand Pablo Picasso, and especially Henri Matisse, a little better.

A Life in Danger

    Lucy, aged 15, lives in Bournemouth with her parents. Her parents aren't poor, and she was at a private school when she started getting bullied. This made her very unhappy and she began to misbehave. She made some new friends who went clubbing a lot. Later she even took drug and stole money to buy drug. Her parents were so worried about their daughter and so angry about her behavior that they decided to send Lucy to Turn-About Ranch (TAR), a tough camp for problem teens in Utah, in the USA.

Lucy didn't like the idea of going to the ranch（牧场）in Utah, but after spending three months there, she's changed her attitude. She said, "The staff at TAR cared about our emotional well-being but they also wanted us to be disciplined and respect the rules. They told us not to take any drugs, not even tobacco or alcohol, and they made us get up at 6.30 a.m. every day and to school work as well as jobs around the ranch. TAR is a real, working ranch with cows and horses, which we had to take care of.

At TAR they asked us not to wear make-up or jewelry or use hair products. They told us that teenagers with problems often use a cool appearance as a mask to hide behind and that they needed to break down those barriers to help us look inside at the confusion which causes our problem behavior. They also wanted us to take responsibility for all our actions."

Her time there has made her more self-confident, less aggressive and much happier. She's started a college course, she's got a part-time job, and she's also doing voluntary work helping underprivileged children. She hasn't taken any drugs since she left TAR. Lucy says, "TAR made me think very hard about the friends I used to see and where my life was going. I realized that the drugs were starting to become the only thing in my life that I cared about, which meant I stopped enjoying other things and treated people badly. I ought to have realized that, and I know I shouldn't have done a lot of things that I did. The ranch has really opened my eyes. They told me to believe I could achieve something with my life, and from now on I want to try."

    Fred Rogers was a curious man, six feet tall and without pretense (虚伪). He liked to pray, to play the piano, to swim, and to write, and he somehow lived in a different world than I did. We became friends for some 20 years, and I made lifelong friends with his wife, Joanne. I remember thinking that it seemed as if Fred had access to another realm (领域) like the way pigeons have some special magnetic compass that helps them find home.

    Fred died in 2003, somewhat quickly, of stomach cancer. He was 74. "Just don't make Fred into a saint (圣人)," That has become Joanne's refrain (叠句). 91 now, still full of energy, she lives alone in the same roomy apartment, in the university section of Pittsburgh, that she and Fred moved into after they raised their two boys. Throughout her 50-year marriage to Fred, she wasn't the type to hang out on the set or attend production meetings. That was Fred's thing. He had his career, and she had hers as a concert pianist. For decades she toured the country with her college classmate, Jeannine Morrison, as a piano duo; they didn't retire the performance until 2008.

    "If you make him out to be a saint, people might not know how hard he worked," Joanne said. Disciplined, focused; a perfectionist — an artist. That was the Fred she and the cast and crew knew. "I think people think of Fred as a child-development expert," David Newell, the actor who played Mr. "Speedy Delivery" McFeely, told me recently. "As a moral example maybe. But as an artist? I don't think they think of that." that was the Fred I came to know. Creating, the creative impulse (冲动), and the creative process were our common interests. He wrote or co-wrote all the scripts for the program — all 33 years of it. He wrote the melodies. He wrote the lyrics. He structured a week of programming around a single theme, many of them difficult topics, like war, divorce, or death.

    I don't know that he cared whether people saw him as an artist. He seemed more intent (急切的) that people not see him at all. The focus was always on you. Or children. Or the tiny things. It was hard to see Fred.

    I like you just the way you are. One day he told me where that core message came from. His grandfather, Fred Brooks McFeely, who like the rest of the Rogers family lived in Latrobe, Pennsylvania, about 40 miles east of Pittsburgh. "He was a character," he said. "Oh, a lot of me came from him."

    His grandfather represented a life of risk and adventure, the very things Fred's boyhood lacked. He was a lonely kid, an only child until he was 11, when his sister came. He was bullied. Here comes Fat Freddie! He was sickly. He had asthma. He was not allowed to play outside by himself. He spent much of his childhood in his bedroom.

    He had music, and he had puppets to keep himself amused. He didn't need much. He was expected to fill his father's shoes, become his business partner at the brick company. "My dad was pretty much Mr. Latrobe," he told me. "He worked hard to accomplish all that he did, and I've always felt that that was way beyond me. And yet I'm so grateful that he didn't push me to do the kinds of things that he did or to become a miniature (缩小的) version of him. It certainly would have been miniature."

    Fred wanted to be like his grandfather. "He taught me all kinds of really neat stuff!" he told me. "I remember one day my grandmother and my mother were telling me to get down, or not to climb, and my grandfather said: ‘Let the kid climb on the wall! He's got to learn to do things for himself!' I heard that. I will never forget that. What a support that was. He had a lot of stone walls on his place." "I think it was when I was leaving one time to go home after our time together," Fred told me, "that my grandfather said to me: ‘You know, you made this day a really special day. Just by being yourself. There's only one person in the world like you. And I happen to like you just the way you are."
