“A room without books is like a body without a soul,” observed the Roman philosopher, Cicero. It can also be a sign of financial problems to come. New research has uncovered a strong connection between the earning of adults and whether they grew up surrounded by books as children.

    Three economists at the University of Padua—Giorgio Brunello, Guglielmo Weber and Christoph Weiss—studied 6000 men born in nine European countries and concluded that children with access to books could expect to earn more money than those who grew up with few or no books.

    They studied the period from 1920 to 1956, when school reforms saw the minimum school leaving age raised across Europe. They booked at whether, at the age of 10, a child lived in a house with fewer than 10 books, a shelf of books, a bookcase with up to 100 books, two bookcases, or more than two bookcases.

    Over the period studied, the research, published in The Economic Journal, found that an additional year of education increased a man's average lifetime earnings by 9%. Men brought up in houses with less than a shelf of books earned only 5% more as a result of the extra year's education, compared with 21% more for those who had access to a lot of books. And those who had access to books were more likely to move to the better-earning opportunities in cities than those without books. The men's first job was also much more likely to be a white-collar job.

    The economists offer a number of theories for the results. “Perhaps books matter because they encourage children to read more and reading can have positive effects on school performance,” they said.

    The number of books in children's homes can effectively predict their cognitive(认知的) test scores. This may indicate a home that encourages cognitive skills, which are important for economic success in life.

    Do you sometimes argue about what seems to you to be a simple fact? Do you argue whether it's cold outdoors or whether the car in front of you is going faster than the speed limit (限速)?

    If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant's trunk (象鼻) said it was like a snake. The second who felt the elephant's side said it was like a wall, while the third said it was like a spear( 矛 ) as he touched the animal's tusk. The fourth, who took hold of the elephant's tail insisted that it was like a rope. The fifth man said it looked liked a tree as he put his arms around one of the elephant's legs. The last, who was tall and got hold of the elephant's ears, said it was like a huge fan.

    Each man's idea of the animal came from his own experience. So if someone disagrees with you about a “simple fact”, it's often because his experience in the matter is different from yours.

    To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water (温水)in the third. Now put your left hand in the hot water. Put your right hand in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it is hot.

    When Ron first started with his organization, he loved his job. He went into work every day filled with purpose and passion (热情). Three years later, however, it was hard to recognize him. Now, Ron detests going to work. He feels that his work is meaningless, he's always stressed, and he calls in sick frequently.

    These are basic symptoms (征兆) of burnout. If you've experienced this yourself, it's important that you should know how to recover from it before you have difficulty in having a sense of satisfaction and then dislike your job.

    You first need to know why you've experienced burnout. First, look at any resentment (愤怒) that you feel towards your work. Often, feelings of resentment point to something important that is missing.

    Here's a good example. Jennifer manages a team around the world, so her workday often starts at 6 a.m. She doesn't mind this because she likes her team and her job. But she feels resentful when her boss forgets that she starts work so early and repeatedly asks her to stay late, which causes her to miss important time with her family.

    In this example, burnout wouldn't happen if Jennifer disliked her job; in fact, she loves what she does. She experiences burnout because she hates missing out on family time in the evenings.

    Take time to think about any negative feelings that you have about your role, and try to get to the root of the problem. Once you've known the cause of your burnout, write down at least one way that you can manage that source of stress. This might include giving some of your duties to others, working from home one day a week, or even changing roles.

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel stressed to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset helps them to learn a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    One morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.

    Though he was tired, Howe slept badly. He turned and turned. Then he had a dream. He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practised sewing machine.

    Elias Howes was not the only one in finding the answer to his problem in this way.

    Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.

    To know the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious(无意识的), but still active part understands your experiences and goes to work on the problems you have had during the day. It stores all sorts of information that you may have forgotten or never have really noticed. It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake. However, the unconscious part acts in a special way. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called “secret messages to ourselves”.

    They say the average person makes 35, 000 decisions a day. Yet in her new book, How Woman Decide, Therese Huston explores a widespread phenomenon that many women fail to notice. "There's a huge double standard when it comes to how men and women are viewed as decision﹣makers," explains Therese, a psychologist from Seattle University. Therese decided to write the book after looking at her bookshelf: At one end, there were bestselling books about how to be a clever decision﹣maker ﹣ all written by men and featuring interviews with men like athletes. At the other end were books aimed at women on gaining leadership skills and confidence.

    "Once those women are at the table, will their decisions be taken as seriously as men's？" Therese wondered. "Men are respected as decision﹣makers more than women, especially in the workplace, largely because there's this cultural belief that women are unable to make smart choices at work. "

    So, Therese set out to pick apart the stereotypes（固有印象）to see what scientific research had found. "Scientific research shows that men and women struggle with decision-making equally. The only disadvantage I found was that during the teenage years-teenage girls are more indecisive than teenage boys. Otherwise, there's little difference between the genders（性别）.

    However, there are some differences. "Women are more collaborative（协作的）, "says Therese. "A female boss is more likely to ask the opinions of those around her when making a choice. Women ask for input, which helps make better decisions. However, this is often seen as a weakness rather than a strength.

    Therese also found that during times of stress, men and women make different choices, and the outcomes are often better when women are involved.

    Study after study backs this view up. Neuroscientists Mara Mather and Nicole Lighthall from the University of Southern California studied the way men and women make decisions and found that in times of stress, they react very differently.

    During their study, which involved playing a virtual gambling（赌博）game, they found that when the females became stressed, they made smart decisions ﹣ quitting while they were ahead or taking safe bets. But when the men became stressed, they did the opposite, risking everything for a slim chance of a big win.
