When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.

These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society,” said George Vaillant, the psychologist (心理学家) who made the discovery. “And because they felt good about themselves, others felt good about them.”

Vaillant's study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men's mental-health scores with their boyhood-activity scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.

Working—at any age—is important. Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn't everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work.”

    A study published in Child Development,the top－ranked educational psychology journal,provides some of the strongest evidence yet that gesturing may have a unique effect on learning.Teachers in the United States tend to use gestures less than teachers in other countries.

     "Gesturing can be a very beneficial tool that is completely free and easily employed in classrooms," said Kimberly Fenn,study co－author and assistant professor of psychology at Michigan State University."And I think it can have long－lasting effects."

    Fenn and Ryan Duffy of MSU and Susan Cook of the University of Iowa conducted an experiment with 184 second－,third－ and fourth－graders in Michigan elementary classrooms.

    Half of the students were shown videos of an instructor teaching math problems using only speech.The others were shown videos of the instructor teaching the same problems using both speech and gestures.In the speech－only videos,the instructor simply explains the problem.In the other videos,the instructor uses two hand gestures while speaking,using different hands to refer to the two sides of the equation.Students who learned from the gesture videos performed better on a test given immediately afterward than those who learned from the speech－only video.

    Another test was given 24 hours later,and the gesture students actually showed improvement in their performance while the speech－only students did not.

    While previous research has shown the benefits of gestures in a one－on－one tutoring－style environment,the new study is the first to test the role of gestures in equivalence learning in a regular classroom.

    The study also is the first to show that gestures can help students transfer learning to new contexts—such as transferring the knowledge learned in an addition－based equation to a multiplication－based equation.

    Fenn noted that U.S.students lag behind those in many other Western countries in math and have a particularly hard time mastering equivalence problems in early grades."So if we can help them grasp this foundational knowledge earlier," she said,"it will help them as they learn algebra and higher levels of mathematics."

    In many big cities, a lot of old people keep birds, cats, dogs and other animals in their houses. These animals are friendly to the old people and never leave them. So the old people love them and see them as their good friends or families.

    It's not difficult to keep these lovely animals at home. But you have to take them to animal hospitals to give them needles (注射), so they won't get ill or they will make people ill. Now there are lots of animal food stores here and there. People can buy good animal food for their animals there. Old people can buy animal food on the phone or on the Internet. But it's a little more expensive.

    Sometimes it's kind of dirty and dangerous to keep animals. They sometimes look dirty and smell terrible and can be dangerous. For example, an old woman in Shanghai lost her life on the street for her pet dog.

    Maybe old people in big cities have many reasons to keep these nice and clever animals. They may feel lonely when their children leave. And these pets can be their great helpers. They are their good friends and help them in many things.

    A large body of research has been developed in recent years to explain many aspects of willpower. Most of the researchers exploring self-control do so with an obvious goal in mind: How can willpower be strengthened? If willpower is truly a limited resource, as the research suggests, what can be done to make it stay strong?

    Avoiding temptation (诱惑）is an effective method for maintaining self-control, which is called the “out of sight, out of mind” principle. One recent study, for instance, found office workers are less attracted to candy in the desk drawer than that on top of their desks, in plain sight.

    The research suggesting that we possess a limited reservoir of self-control raises a troubling question. When we face too many temptations, are we to fail? Not necessarily. Researchers don't believe that one's willpower is ever completely exhausted. Rather, people appear to hold some willpower in reserve, saved for future demands. The right motivation allows us to tap into those reserves, allowing us to carry on even when our self-control strength has been run down. High motivation might help overcome weakened willpower—at least to a point.

    Willpower may also be made less vulnerable (脆弱) to being exhausted in the first place. Researchers who study self-control often describe it as being like a muscle that gets tired with heavy use. But there is another aspect to the muscle comparison, they say. While muscles become exhausted by exercise in the short term, they are strengthened by regular exercise in the long term. Similarly, regular practices of self-control may improve willpower strength.

    The evidence from willpower-exhaustion studies also suggests that making a list of resolutions on New Year's Eve is the worst possible approach» Being exhausted in one area can reduce willpower in other areas, so it makes more sense to focus on a single goal at a time. In other words, don't try to quit smoking, adopt a healthy diet and start a new exercise plan at the same time. Taking goals one by one is a better approach. Once a good habit is in place, Baumeister says, you'll no longer need to draw on your willpower to maintain the behavior. Eventually healthy habits will become routine, and won't require making decisions at all.

    Many questions about the nature of self-control remain to be answered by further research. Yet it seems likely that with clear goals, good self-monitoring and a little practice, you can train your willpower to stay strong in the face of temptation.

    I was driving down the road the other day, listening to sweet music coming out of my car radio. My heart felt peaceful, my mind was clear, and my soul was full of love. Even with all its problems: life seemed good. Then the music stopped and the news came on. There was talk of another famous millionaire in drug rehab (康复) after an incident with the police. There was news on the murder of a poor man whose life was supposed to be changed after winning the lottery. There was even a discussion on how much greed and excess (放肆) had damaged our world.

    Every story seemed to point once again to the old saying that money can't buy happiness. Hearing them made me think of a movie I saw many years ago on Mother Teresa's home for the dying in India. What struck me most when I watched it wasn't the unbearable poverty there. It wasn't the sickness and suffering that the people there were going through. It was rather the peaceful smiles of love, kindness, and happiness that they shared with the Sisters and with each other. These people had nothing. Many were struggling at the end of death. Yet, they knew the simple truth that so many of us here are still learning: Joy is Free.

    We can have joy and spread joy every day of our life here. Don't love or admire dollar signs and think that money will bring you happiness then. Joy can't be purchased. It can't be owned. It can only be chosen and then given freely to others. In the eyes of eternity (永恒), money is only worthless paper. The only thing that matters is the love within you and the love that you give to the world. Make that your legacy (遗产) and your life will forever be rich in joy.
