Recently my husband had his Achilles tendon（跟腱） cut when feeding a chicken. When sitting in the doctor's office waiting for surgery stressfully, I decided to treat myself for a minute and start to read about “The Little House on the Prairie”. Suddenly I felt my life seemed like a slack（懈怠） compared to the Ingalls who do all their washing and cooking but they feel so happy. Their every happiness is created from the work with their own hands. Yet I'm walking around feeling sorry for myself because I'm picking up the slack! So I'm thinking “Work it out! Get up and get busy.”

    It really is true. I realize that I'm happiest when accomplishing tangible(有形的) productive work—working in the yard and washing my dishes—brings me happiness. This does not surprise Kelly Lambert Ph.D. She has been researching the phenomenon she calls “effort-rewards”. When you do meaningful work with your hands, a kind of neurochemical feedback floods your brain with dopamine and serotonin. These happy brain chemicals are natural antidepressants, and we've evolved to release them both to reward ourselves for working with our hands and to motivate ourselves to do it some more. Dr. Lambert says Americans have become more depressed in recent years and at the same time we've experienced a decrease in purposeful physical activity. Did we lose something vital to our mental health when we started pushing buttons instead of ploughing the fields?

    Dr. Pansinski says she gets that happy look when she prepares a meal at the end of a day. “We are programmed to reward ourselves when we accomplish things with our hands. For so many people, it just feels as though everything's going so fast—life, kids, hundreds of e-mails a day. There is so little you can really see and hold on to. Working with one's hands is a way to slow down, to take pleasure in life again.”

    The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.

    Considering the negative effects of not sharing a story in the news, people are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

    There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked(透漏), their power to destroy is set free."

    There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.

    Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.

    Honesty and openness is important: It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.

    Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.

    Almost one in five drivers had dozed off behind the wheel, a shocking news report had showed. Of those who were dozing off, 29% have done so with their cars speeding at 70 miles per hour. The report also found a quarter of men have fallen asleep while driving, making it almost twice as many as women.

    The Safety on Wheel Report, by Post Office Insurance, also looked at how often tiredness or a lack of concentration caused accidents. Three in ten drivers have experienced an accident, from passing a walker crossing to hitting another vehicle, because of a lack of concentration. Meanwhile, almost half (49%) of UK drivers have driven when they do not concentrate.

    Paul Haven hand, head of insurance at Post Office, said, “ When tiredness strikes, drivers should avoid the roads.” There is no measurement for tired driving, unlike driving under the influence of alcohol, yet it could result in an equally dangerous accident.

    Drivers are advised to take a 15-minute break from driving every two hours. However, a third (36%) are so eager to reach their destination that they will ignore feelings of tiredness. What's more, almost one in five (18%) will drive for longer than four hours without a break, while 6% carry on for up to 6 hours. Just over a quarter (27%) choose a quick stop to buy a cup of coffee, which is a very popular way for drivers to get rid of tiredness, and only 17% stop to have a rest until they feel energetic again. Mr. Havenhand added, “Drivers should plan ahead and rest before starting a long journey; besides, they can take regular breaks to recharge their batteries while on road; in some cases, if they do feel too tired to concentrate on the roads, they could consider an alternative means of transport.”

    There is a story about a man who lost his legs and left arm in an accident. After the accident, only a finger and thumb on his right hand remained.

    He was a brilliant, creative, and educated man. He had gained a lot of experience while traveling around the world, so he became very depressed after his accident. He was afraid that he would spend the rest of his life suffering and would no longer be able to spend his life in a meaningful way. Then, he realized that he still had partial function of his right hand and could still write even though it was very difficult. An idea occurred to him, “Why not write to other people who need encouragement?”

    He wrote to the prison ministry about sending letters to the prisoners. The prison minister replied, “Writing to the prisoners is acceptable, but your letters will not be answered.”

    Filled with excitement, the man knew he could write his letters. He began sending one-way messages of God's love, hope, strength, and encouragement. He wrote twice a week, testing his strength and ability to the limit. He poured his heart and soul into his words and shared his experience, sense of humor, optimism, and faith.

    It was difficult to write those letters, especially without hope of a reply. One day he received a letter from the prison ministry. It was a short note from the officer who monitored and checked the prison mail.

    The letter said, “Please write on the best paper you can afford. Your letters are passed from room to room until they fall to pieces!”

    No matter what circumstances life may present, we all have unique experiences, abilities, and God-given talents. We can discover ways to reach others who desperately need messages of encouragement and strength.

    English is full of colorful phrases to describe shyness. Someone shy might be called shrinking violet or a wallflower, while for especially nervous types we have the curious expression: they wouldn't say boo to a goose.

    None of these are traditionally seen as positive descriptions, even if you like geese. In a culture of go-getting, high achievers, shy people don't come first. Or that's what the self-help industry would have you believe. Bookshops are filled with vital tomes(巨著) that promise to help beat social fears and find success in life, love and business. That is why one book, Shrinking Violets: A Field Guide to Shyness, bucks the trend. It became a sudden success across English-language media recently for its new take-on shyness.

    Author Joe Moran says that despite struggling with shyness and longing for loneliness all his life, being shy can also be "a gift". Freed from the constant urge to participate and compete in social situations, people are liberated to look at the world in new ways, and gain fresh insights.

    Indeed, many of the world's great thinkers and artists are introverts(内向的人). Scientists Charles Darwin and Albert Einstein preferred their own company; actress Keira Knightley often finds herself tongue-tied at parties; and Harry Potter author JK Rowling claims she used to be too nervous to even borrow a pen.

    Moran told BBC Future: "I think shyness probably does turn you into an amateur anthropologist(人类学家), really-you are more likely to be an observer."

    So, while extroverts make all the noise, they don't necessarily have the best ideas.

    If you're shy, you've probably known this for a long time. You just don't shout about it.

    Astronomy (天文学) is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about heavens(天堂). But the six planets that he could see with his eyes alone limited man.

    The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.

    Each new tool added to the field of astronomy helped man reach out into space. Until there were telescopes(望远镜), man did not know much about the moon. He did not know that the planet called Saturn(土星) had rings around it. His sight was so limited that he could not see all the planets. In the early 1700s, people thought there were only six planets. Pluto (冥王星), the last of the nine planets to be discovered was seen until 1930.

    Before the spectroscopes (分光镜), man didn't know what kind of gas was in the sun or other stars, without radio telescopes(射电望远镜), we did not know that radio noise came from far in space.

    Today, astronomy is a growing science. We have learned more in the past fifty years than in the whole history of astronomy.
