We live in a culture that sends out very mixed messages about mistakes: We're told we learn by making them, but we work hard to avoid them. So the result is that most of us know that we are going to make mistakes, but deep down, we feel we shouldn't.

    Experiments with schoolchildren who did well on a given test show that those who were praised for being smart and then offered a more challenging or less challenging task afterward usually chose the easier one. On the other hand, children praised for trying hard— rather than being smart—far more often selected the more difficult task.

    If we try hard to avoid mistakes, we aren't open to getting the information we need in order to do better. In a writing study, experiments showed that those who are so scared to make mistakes perform worse in writing tasks than those who aren't as worried about being perfect. They fear receiving any kind of negative feedback, so they don't learn where they went wrong and how to get better.

    We don't just learn more when we're open to mistakes, we learn deeper. Research tells us that if we're only concerned about getting the right answer, we don't always learn the underlying concepts that help us truly understand whatever we're trying to figure out. Mistakes need to be seen not as a failure to learn, but as a guide to what still needs to be learned. As Thomas Edison said, “I am not discouraged, because every abandoned wrong attempt is another step forward."

    Furthermore, we often make mistakes because we try new things—we wander away from accepted paths. Teflon, penicillin—these are examples of great discoveries made by mistake. Take a page from Albert Einstein, who said, "Anyone who has never made a mistake has never tried anything new. "

    E-mail has been widely used since its invention for its convenience, efficiency, and high speed. However, it is wise to remember how easily this wonderful technology can be misused, sometimes unintentionally, but can result in serious consequences.

    Now let's look at the case of the Illinois man who left the snow-filled streets of Chicago for a vacation in Florida. His wife was on a business trip and was planning to meet him there the next day. When he reached his hotel , he decided to send his wife a quick E-mail. Unable to find the note with his wife's E-mail address, he did his best to type from his memory. Unfortunately, he missed one letter and his E-mail was directed to an elderly lady whose husband had passed away (去世) only the day before. When the sad widow checked her E-mail, she took one look at the screen, let out a sharp cry, and fell to the floor in a dead faint (昏迷 ). At the sound , her family rushed into the room and saw this note on the screen:

    MY DEAREST WIFE： JUST GOT CHECKED IN. EVERYTHING PREPARED FOR YOUR ARRIVAL TOMORROW.

    P.S. SURE IS HOT DOWN HERE

    What might the future be like? Here are some predictions: things to come, things to go.

    Spring Festival, the most important Chinese holiday when everyone returns home has caused headaches for millions of Chinese. More than 2 billion people travel at the same time, making getting travel tickets and the journey difficult. But in 28 years, Spring Festival travel may not be a problem at all. China plans to build more than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by 2020.

    And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem.

Newspapers will come to an end in 2043. In the future, digital newspapers will be sent to personal web tools through Internet. Readers can discuss topics with journalists and editors. Information will move faster.

    Oil is running out faster than expected. But scientists have found something else for oil as fuel. Coal, natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy.

    Schools will go electronic. Computers will be important and popular among the students. Everything will be in the computer and students will not need to bring books to school. They will find information on the Internet. A computer will be the students ‘library, schoolbag and connection to the outside world. There will be robot teachers, who will check homework on computers and communicate with the students' parents through e-mail. And school buses will be like spaceships, comfortable and safe.

    Some places in the world have strange laws. It's important for you to know about them before going there.

    Whoever likes to chew gum(口香糖) may have to leave Singapore. The government really wants to keep the city clean and will fine you for chewing gum.

     Before you leave for the United Arab Emirates you'd better make sure you aren't visiting during Ramadan(斋月). During that time you aren't allowed to eat or drink in public. Tourists have been fined up to $275 for drinking in public.

    Lovers spend so much time kissing each other goodbye at train stations that trains often start late. This law— no kissing your lover goodbye at train stations – is rather old, and isn't in use today in France.

In Thailand it's against the law to drive a car or motorcycle without a shirt on, no matter how hot it is. Punishments are different in different areas and can include warnings and tickets costing about $10. No joke — the local police will stop you.

     Studies in Denmark have shown that cars with their headlights on are more noticeable by other drivers than those with their headlights off. Drivers there are required to leave their headlights on even during the day, or they may face a fine up to $100.

    Do you often buy things using coins? Don't do it in Canada. The Currency Law of 1985 doesn't allow using only coins to buy things. Even the use of the dollar-coin is limited (受限制的). The shop owner has the right to choose whether to take your coins or not.

    Make sure you know about these laws before your next trip. Better safe than sorry.

Perhaps you think you could easily add to your happiness with more money. Strange as it may seem, if you're unsatisfied, the issue is not a lack of means to meet your desires but a lack of desires—-not that you cannot satisfy your tastes but that you don't have enough tastes.

    Real riches consist of well-developed and hearty capacities to enjoy life. Most people are already swamped with things. They eat, wear, go and talk too much. They live in too big a house with too many rooms, yet their house of life is a hut.

    Your house of life ought to be a mansion, a royal palace. Every new taste, every additional interest, every fresh enthusiasm adds a room. Here are several rooms your house of life should have.

    Art should be a desire for you to develop simply because the world is full of beautiful things. If you only understood how to enjoy them and feed your spirit on them, they would make you as happy as to find plenty of ham and eggs when you're hungry.

    Literature, classic literature, is a beautiful, richly furnished room where you might find many an hour of rest and refreshment. To gain that love would go toward making you a rich person, for a rich person is not someone who has a library but who likes a library.

    Music like Mozart's and Bach's shouldn't be absent. Real riches are of the spirit. And when you've brought that spirit up to where classical music feeds it and makes you a little drunk, you have increased your thrills and bettered them. And life is a matter of thrills.

    Sports, without which you remain poor, mean a lot in life. No matter who you are, you would be more human, and your house of life would be better supported against the bad days, if you could, and did, play a bit.

    Whatever rooms you might add to your house of life, the secret of enjoying life is to keep adding.
