About 30 years ago, I left Cuba for the United States with my son. After getting settled finally in Brunswick, New Jersey, I enrolled(注册) my son in kindergarten. Several weeks later, my son's teacher asked me to meet him at his office.

In the teacher's office, and exchange of greetings was followed by his questions: “Is your son mentally retarded(弱智的)？Does he suffer from any kind of mental disability?”

Was he talking about my wonderful Scola? NO, no, it can't be. What a helpless, lonely moment! I told him that Scola was a quiet, sweet little boy, instead. I asked him why he was asking me all these questions.

My son could not follow the teacher's directions, he told me, and thus, Scola was disrupting the class, Didn't he know my son did not speak English yet?

He was angry; “Why hasn't your son been taught to speak English? Don't you speak English at home?”

No, I didn't speak English at home, I replied. I was sure my son would learn English in a couple of months, and I didn't want him to forget his native language. Well, wrong answer! What kind of person would not speak in English to her son at home and at all time? “Are you one of those people who come to this country to save dollars and send them back to their country, never wanting to be a part of this society?”

    Needless to say, I tried to tell him I was not one of “those people.” Then he told me the meeting was over, and I left.

    As I had expected, my son learned to speak English fluently before the school year was over. He went on to graduate from college and got a job, earning close to six figures. He travels widely and leads a well-adjusted, contented life. And he has benefited from being bilingual(双语的)。

    Speaking more than one language allows people to communicate with others; it teaches people about other cultures and other places—something very basic and obviously lacking in the “educator” I met in New Jersey.

    Did you know that something as simple as the wallpaper on your computer can tell people a lot about you? According to researcher Donna Dawson,our computers say something about what we're like because they are part of our “personal space.”

    A picture of a child or family on the screen often means the person cares deeply about their loved ones.A photo of the person surrounded by friends shows they value their popularity and probably work well with other people.On the other hand,pictures showing examples of past successes,like winning a prize may mean a person is only interested in themselves.

    Pictures of nature and natural scenery tell people that you are driven to succeed and use the pictures to relax and remove the pressure（压力）in your life.Cityscapes,pictures of cities or towns,show that you enjoy travel and adventure.Most people with cityscapes as their wallpaper are optimistic（乐观的）,happy people who feel even better thinking about the places they've visited or want to visit.

    Pictures of animals show that you are optimistic and kind-hearted.You are often happy and you enjoy life and act young.Cartoons（漫画）or drawings show that you are a multitasker,someone who does many things at once.You have many responsibilities,but you deal with them well.That's one reason you like having something to smile about when you look at your computer wallpaper.

    Then,what does plain blue wallpaper tell us about a person?According to Dawson,a person with plain blue wallpaper probably values their privacy and keeps work from becoming too personal,

    Last week I did something that scared me. I stood in front of nearly 200 financial planners and I talked to them about why financial blogs are a good thing. I'm a confident writer. I've been doing this long enough that I know my strength and my limitations. I'm less confident as a speaker. I don't have time to pause to collect my thoughts. I'm not able to edit. I'm afraid of being trapped in a corner without being able to talk my way out. Basically, I'm scared to speak.

    It would be easy to simply refuse the chances that come my way. When somebody asks me to speak in front of a group, I could say "no". When radio and television stations call for an interview, I could say "no". But for the past two years, I've been following my own policy to say "yes" to new chances.

    To say "yes" is to live in fear. My goal is to continually improve myself to become better than I am today. One way to do that is to do the things that scare me, to take them on as challenges, and to learn from them—even if I fail.

    In mid-November, a local station asked me to appear on live television. "I realize it's short notice," the producer wrote, "but we'd love to have you on the show if you're available tonight." I was frightened. I thought about recent taped television interviews that I had hated. I was afraid of what might happen.

    But I also thought about the things that had gone right. I thought of how my speaking skills had improved over the past year. And then I thought of the book I was reading, a book that I had bought for $1.29 at the local store. The Magic of Thinking Big was a huge bestseller during the 1960s. Written by Dr. David Schwartz, a professor at Georgia State University, the book contains dozens of practical tips on how to take risks to achieve big goals. Schwartz argues that nobody will believe in you until you believe in yourself.

    So when the television producer asked if I wanted to appear on his show, I thought big. "Sure," I said. "I'll do it." I acted confidently, but on the inside I was frightened. What I needed was techniques to build up my confidence and to overcome my fear.

    In the first year or so of Web business, most of the action has revolved around efforts to tap the consumer market. More recently, as the Web proved to be more than a fashion, companies have started to buy and sell products and services with one another. Such business-to-business sales make sense because business people typically know what product they are looking for.

    However, many companies still hesitate to use the Web because of doubts about its reliability. "Businesses need to feel they can trust the pathway between them and the suppliers," says senior analyst Blane Erwin of Forrester Research. Some companies are limiting the risk by conducting online transactions only with established business partners who are given access to the company's private Internet.

    Another major shift in the model for Internet commerce concerns the technology available for marketing. Until recently, Internet marketing activities have focused on strategies to "pull" customers to sites. In the past year, however, software companies have developed tools that allow companies to "push" information directly onto consumers. Companies such as Virtual Vineyards are already starting to use similar technologies to push messages to customers about special sales, product offerings, or other events. But push technology has earned the contempt of many Web users. Online culture thinks highly of the notion that the information flowing onto the screen comes there by specific request. Once commercial promotion begins to fill the screen uninvited, the distinction between the Web and television fades. That's a prospect that horrifies Net purists.

    But it is nearly inevitable that companies on the Web will need to resort to past strategies to make money. A Web site selling the right kind of products with the right mix of interactivity, hospitality, and security will attract online customers. And the cost of computing power continues to free fall, which is a good sign for any enterprises setting up shop in silicon. People looking back 5 or 10 years from now may well wonder why so few companies took the online plunge.
