Many of us mistakenly believe that it's wrong to think we have any good qualities. We may spend a lot of time blaming ourselves for our negative qualities, thinking that self criticism is the key to improving our performance. However, a constant focus on our supposed shortcomings can stop our efforts to make friends with other people. How can we believe that others could like us if we believe our inner being is flawed (有缺陷)?

    If someone seems to dislike you, the reason for that dislike might have little or nothing to do with you. The person who doesn't like you might be fearful, or shallow, or busy or shy. Perhaps you and that person are simply a mismatch for each other at this particular time.

    Don't take yourself out of the game by deciding that your flaws are bigger than your good qualities. In fact, some of the very qualities you consider to be flaws may be irresistible to someone else. For all the factors that might cause one person to reject you, there are at least as many factors that will work in your favor with someone else.

    You might be thirty pounds over your ideal weight, but you may have a wonderful laugh and a real enthusiasm for life. There are many people who don't mind your extra pounds. You may drive a shabby car, but you might be a great dancer and a loyal friend. There are people out there looking for loyalty, or fun, or sweetness, or wisdom, and the package it comes in is not important. If you are worried that you are not beautiful enough to attract friends, keep in mind that not everyone is looking for physical beauty in their friends. You can decide to feel inferior (自卑) because you don't have much money and you don't drive a nice car. You can believe that this is the reason that you don't have many friends in your life. On the other hand, if you are very wealthy you may be suspicious that everyone is after your money and that nobody really likes you as a person.

    The point is that you can focus on just about anything and believe it's the reason you do not have friends and cannot make any.

    What makes a building ugly? Everyone's got their own opinion, so it's hard to say. Now, let's take a look at some of the world's worst buildings.

    The Torre Velasca

    The Torre Velasca in Milan is in the centre of Milan(Italy). The tower, which went up in the 1950s, is about 100 metres tall. Its design is actually a modern representation(代表) of a traditional Lombard castle, where the lower parts were narrower than the upper parts.

    The Mirador Building

    The Mirador Building in Madrid(Spain)was created by Dutch studio MVRDV and the Spanish architect(建筑师)Blanca Lleó.The building, which is a block of flats, opened in 2005. There is a large rectangular(矩形的)hole in the upper part of it, which is used by the neighbourhood as a meeting area and playground.

    The Prague TV Tower

    The Prague TV Tower is in Prague(the capital of the Czech Republic). It stands 216 metres high and looks a bit like a tall, thin space ship. Prague is famous for its architectural beauty, so when the tower was put up in 1985 by architect Vaclav Aulicky and engineer Jiri Kozak, many felt it didn't fit in.

    The Longaberger Basket Company

    The Longaberger Basket Company building is in Newark, Ohio(USA). The office block was opened in 1997 and looks like a very large basket. It's got seven floors and two handles(把手)at the top. The handles weigh about 150 tons. It may not be the ugliest building in the world but it's certainly one of the most unusual.

    People generally like to pick out the best-looking fruits and vegetables when shopping for produce, but Canadian supermarket chain Loblaws is attracting customers with badly-shaped and imperfect produce at the price of 30% lower than normal-looking ones.

    A trial run of the ugly food line, named "Naturally Imperfect", began with only apples and tomatoes to choose from. Consumer(消费者) demand has been so huge that Loblaws is going to introduce more ugly vegetables and fruit like onions and mushrooms.

    All the produce that will be sold through Naturally Imperfect would otherwise have been used in juices, sauces, or soups, or have not been harvested at all. The director Dan Branson explained that this program benefited both food producers who would otherwise have to let abnormal produce go to waste, and consumers who could buy fresh produce at low prices. And he was right, considering how popular the line has become.

    "It really went well beyond our expectation," Branson said. "I think it really spoke to the fact that Canadians are out there really looking for some Choices."

    Of course, Canadians know that beauty is more than skin(外皮) deep, and they also recognize that they get the same flavor and nutritional (营养的) benefits in spite of appearances. The positive response to the offering of apples and potatoes showed the opportunity to expand the line and offer more choices at a greater price to Canadian families.

    "If you grow produce in your backyard, there will be a lot of produce that won't look as pretty as what you will see in a grocery store", said Branson. "And nature doesn't grow everything perfectly. I'd like to think if somebody were to take a NO Name Naturally Imperfect apple, put it right beside a No. 1 apple, close his eyes and eat them, there would be no difference."

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play, catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, extra learning trials (尝试) increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables (乘法口诀表) are an exception (例外) to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

Young people are spending more time in digital spaces. The Internet allows us to connect with people, share ideas, be creative, have fun and discover new things. Unfortunately, young people also face risks online. Common problems include cyberbullying（网络欺凌）, receiving unwanted messages, seeing images and content you don't want to see, or having your private information or photos shared without your permission.

Safer Internet Day（SID）is organized in the second week of February every year, and over 180 countries take part. The aim is to raise awareness of online issues and make the Internet a safer place. SID invites everyone to be part of a big conversation about online issues. This is particularly important for teenagers because they often experience unpleasant situations online, but they don't always feel they can talk about them.

Cyberbullying is when someone uses the Internet to embarrass, threaten or hurt another person. If you experience cyberbullying, talk to an adult you trust as soon as possible. Don't reply to any messages but save the evidence.

Going online often means spending time alone. When you feel down, social media can make you feel lonelier. Using social media might be related to higher levels of depression. So you need healthy social media use.

Whatever app you use, make sure you know who sees your posts and personal information. Limit what people can see, decide who can comment on your content and thwart other users' comment. It may be illegal to share a photo or video of someone without their permission. The SID's website has advice about what to do if someone shares pictures of you that you feel embarrassed about.

There is still a lot we don't know about how time spent online affects people's well-being. But talking about all the issues helps everyone understand common problems and know how to deal with them.

Damarie Thomas, a twelve-year-old Jamaican teen, was concentrating on practising his skills for the upcoming football contest when he felt a hard tackle(抢断球) from behind, which pushed him to the ground. His world changed overnight. Though his injuries did not result in paralysis(瘫痪), they were serious enough to affect his movement. It was the last time that he had played football.

Now Thomas is an adult and he uses a wheelchair to travel distances. Despite a number of difficulties, he perseveres in his attempts to walk. He proudly claims that from being able to move only two steps at a time, he can now do five steps unaided. Limited resources have influenced his treatment, but he is hopeful that he will be able to complete recovery soon. Having an experience like this would have broken many an adult, but not this young man. "It's not what happens but how you come back from it that counts," he said.

After his injury, Thomas did well in his primary school exams and gained a place at one of the top-rated high schools in Jamaica. However, at that time the school was not equipped to accommodate a physically disabled student and he had to accept a transfer to a high school near his home.

It is a blessing that Thomas has now signed up for an information technology course at Abilities Foundation, proudly claiming his improvement by learning coding(编码). The Abilities Foundation aims to equip the disabled with skills through training. The training centre encourages Thomas to chase his dream — he wants to become a successful software engineer, creating innovative technology accessible and beneficial to all, especially people with disabilities.
