Five years ago, when I taught art at a school in Seattle, I used Tinkertoys as a test at the beginning of a term to find out something about my students. I put a small set of Tinkertoys in front of each student, and said:"Make something out of the Tinkertoys. You have 45 minutes today and 45minutes each day for the rest of the week." A few students hesitated to start. They waited to see the rest of the class would do. Several others checked the instructions and made something according to one of the model plans provided. Another group built something out of their own imaginations.

    Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect(感染) other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, "But I'm just not creative."

"Do you dream at night when you're asleep?"

"Oh, sure."

"So tell me one of your most interesting dreams." The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. "That's pretty creative. Who does that for you?"

"Nobody. I do it."

"Really-at night, when you're asleep?"

"Sure."

"Try doing it in the daytime, in class, okay?"

    In 1943, when I was 4, my parents moved from Coeur d'Alene, Idaho, to Fairbanks, Alaska, where adventure was never very far away.

We arrived in the summer, just in time to enjoy the midnight sun. All that sunlight was fantastic for Mom's vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didn't care much about my bedtime.

    Dad was a Railway Express agent and Mom was his clerk. That left me in a mess. I usually managed to find some trouble to get into. Once I had a little Are going in the dirt basement of a hotel. I had tried to light a barrel（桶） of paint but couldn't really get a good fire going. The smoke got pretty bad, though, and when 1 made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me

    Mom and Dad were occupied in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mom rescued me. 1 hadn't turned 5 yet.

    As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue on a metal handrail at school?

    As for Leonhard Seppala, famous as a dog sledder (驾雪橇者), I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didn't realize what a superstar he was, but I do remember the ride well. I was wrapped (包裹) heavily and well sheltered from the freezing and blowing weather.

    In 1950, we moved back to Coeur d'Alene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.

    Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it.

    “There are many better ones available now. It's time to upgrade(更新）my phone.”

    Li's impatience is shared by many. Shortly after the season when new products are released（发布，发售）, many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.

    As consumers' minds are occupied by Apple's newly released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: “Do we really need the latest upgrades?”

    According to Donald Norman, an American author, “planned obsolescence (淘汰）” is the trick behind the upgrading culture of today's consumer electronics industry.

    Electronics producers strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.

“This is an old-time trick—they're not inventing anything new,” Norman said. “This is a wasteful system through which companies--many of them producing personal electronics-- release poor-quality products simply because they know that, in six months or a year, they'll put out a new one.”

    But the new psychology of consumers is part of this system, as Norman admitted, “We now want something new, something pretty, the next shiny thing.” In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world's biggest PC maker, it was only 7 percent.

    Apple's annual upgrades of its products create sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are slight.

    As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.

    “Some games require better hardware to run,” said Li. “If you don't join in, you lose part of the connection to your friends.”

    Life's greatest joys and its greatest sorrows often come from the relationships we have developed with others. In fact, our existence is quite dependent upon this interaction with other individuals (个人) and groups of individuals.

    In our world today, it seems that most people struggle for happiness through pleasant physical surroundings and economic security. These are great, but if there is conflict in human relations, these things do not bring happiness. Think about the last time you were having an argument or a disagreement with one of your co­workers, your boss, your friend, or a family member. Even though you might have been having some success in many areas of your life, did you find yourself still feeling some discomfort due to the stress in that particular relationship? On the contrary, you may know people who are happy in great poverty and with physical stress if they have meaningful, pleasant relations with people around them.

    Consider the best relationship that you have ever had with any individual. To some degree it probably is or was marked by absolute honesty, deep levels of trust, respect for that person's skills, knowledge, or capabilities, open communication, acceptance of different views, and little concern for images.

    In effort to make the relationships we currently have the best that they can be, remember that persuasion usually cannot take place unless there is some sort of close, meaningful connection between the two people involved. The result will be a relationship of respect and progression.

    Many of us have difficulty in accepting the faults and weaknesses of others: co­workers, work leaders, family members, or members of our social or religious groups. Our tendency to demand perfection of others can cause us to lose sight that we, ourselves, are less than perfect.       
    Undoubtedly, there are differences among us. Some of us are even cruel and unpleasant. Others may have cultural differences that are blocks that affect us. But learning to look for the similarities instead of those things that set us apart, bearing differences, and seeing the best in others rather than the worst will lead to relationships of deep respect and lasting value.

    It's natural to think about what goes into producing the food in your daily lunch bag. But have you ever stopped to consider the production techniques behind the bag itself? At the center of it is a woman named Margaret Knight.

    From her earliest years, Knight was a restless creator. In the article titled "TheEvolutionoftheGroceryBag", its writer mentions a few of her childhood projects. She was "famous for her kites", and "her sleds were the envy of the town's boys."

    To support her mother, she took a job at a cotton factory when she was 12. That same year she invented a shuttle system which helped to prevent injury. At the time,  she had no concept of patenting(得到……的专利权) her idea. What strengthened her place in history was her working experience at the Columbia Paper Bag Company. Here, instead of folding every paper bag by hand, Knight wondered if she might be able to make them cleanly and rapidly via an automated machine. The result was a working model of her elegant paper-folding machine. But this time, she wanted to go to the extra step and secure a patent on her creation, a brave move for a woman in the 19th century, when an extremely small percentage of patents were held by women.

    Not only did Knight file for a patent, she bravely defended her ownership of the bag machine idea. A man named Charles Annan said the creation was his own, arguing no woman could be able to design such a machine. Knight fought a legal battle against him and handed Annan a courtroom(法庭) defeat by presenting her detailed hand－drawn blueprints. Finally, Knight received her rightful patent in 1871.

    After making the machine, she continued to invent many other things like a paper feeding machine and a skirt protector. Knight, at the age of seventy, worked twenty hours a day on her 89th invention.

    It has been a year since I found out my friend had passed away. I still store his phone number, even though I know calling the number will never reach him again. I feel like if I deleted (删除) his phone number, it would mean he was really gone.

    Over the past few years, we have planned to travel together just to see the dolphins in the sea. However, for some reasons it didn't happen, yet I always took his calls over the years. We shared a lot of interests.

    When I knew that he had been diagnosed (诊断) with a very serious illness and was in hospital, I remembered sending messages to him. I did not receive a message back, so I left a voicemail. A week later, I sent him a message once again. However, I still didn't get a reply. I thought he was busy. During the next several months I was very busy, too. Suddenly, in that mid-summer, I received a short message: "Sorry, Marlynn, He has passed away."

    I was very sad and surprised at the words. I was very sad and regretful. I regretted that I let the months pass without trying again. I worked with many people who had also lost their best friends. The sadness is often unspeakable. There is guilt (内疚), helplessness and sadness that is difficult to put into words.

    Now I try to be grateful for the times and memories we have. I realize the best thing that we can do is value the ones we love.
