Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Surely we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics，but sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you build a positive self-image and learn to love yourself.

    Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

    The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.

    It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.

    The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat yourself on the back，you'll know you're well on your way. Good luck!

    There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy, the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.

    People who are to be happy fix their attention on the convenience of things. The pleasant parts of conversation, the well prepared dishes, the goodness of the wine, the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend (hurt) many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation. It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.

    Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they want to get some advantages in social position or fortune(财), nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections（反对）, no one will defend or excuse them, and many will join to criticize their wrong doings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact(接触) with them. Otherwise, it can be unpleasing and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.

    Here is a record of the discussion about AI (artificial intelligence) conducted by several scientists:

    Scientist A: I would say that we are quite a long way off developing the AI, though I do think it will happen within the next thirty or forty years. We will probably remain in control of technology and it will help us solve many of the world's problems. However, no one really knows what will happen if machines become more intelligent than humans. They may help us, ignore us or destroy us. I tend to believe AI will have a positive influence on our future lives, but whether that is true will be partly up to us.

    Scientist B: I have to admit that the potential consequences of creating something that can match or go beyond human intelligence frighten me. Even now, scientists are teaching computers how to learn on their own. At some point in the near future, their intelligence may well take off and develop at an ever-increasing speed. Human beings evolve biologically very slowly and we would be quickly substituted. In the short term, there is the danger that robots will take over millions of human jobs, creating a large underclass of unemployed people. This could mean large-scale poverty and social unrest. In the long term machines might decide the world would be better without humans.

    Scientist C: I'm a member of the Campaign to Stop Killer Robots. Forget the movie image of a terrifying Terminator stamping on human skulls and think of what's happening right now: military machines like drones, gun turrets and sentry robots are already being used to kill with very little human input. The next step will be autonomous “murderbots” following orders but finally deciding who to kill on their own. It seems clear to me that this would be extremely dangerous for humans. We need to be very cautious indeed about what we ask machines to do.

    After four silent years, the 27-year-old British singer Adele Adkins has finally introduced herself to the world again with Hello, the opening song from her third album (专辑) 25, which will come out on Nov. 20.

    Although Adele is a very successful singer now, music wasn't always what she saw herself doing. At age 10, when she saw her grandmother's pain over the death of Adele's grandfather, she pictured herself as a heart surgeon.

    "I want to fix people's hearts," she told the UK music website i-D, remembering the childhood interest she'd had in biology classes until she found out that her real talent was for singing.

    Adele didn't go to medical school, but many would agree that she still has healing (治愈) powers. "Her songs find the kind of memory every listener holds somewhere in their hearts. This kind of feeling is what people have always liked in Adele," said The Telegraph. "She writes a pop diary, sharing the simple secrets of her heart."

    Most successful pop stars make albums at a fast pace, but not Adele. After her second album 21 won the 2012 Grammy Award for Album of the Year, she made it clear with her label that she would spend "four or five years" making her next album. She told Vogue magazine, "I won't come out with new music until it's better than 21."

    Instead of seeking fame, Adele remained silent and moved to the countryside. In her free time, she loved to watch TV series Teen Mom, American Horror Story, and The Waling Dead.

    Living life as normally as possible is important to the singer's art. "Nobody wants to listen to a record from someone who's not living in the real world," Adele told i-D, "So I live a low-key life for my fans."

    Breathing dirty air comes at a high price. Air pollution lowers the average life spans (寿命) by a year worldwide and in more polluted parts of Asia and Africa, dirty air shortens lives up to twice that much. Scientists shared their new findings in Environmental Science & Technology Letters. The study used data gathered in 2016 as part of a project known as the Global Burden of Disease and was the first major country-by-country look at the connection between the length of life and what's known as fine PM.

    Air pollution has been linked to many health problems. Most earlier studies had looked at how tiny air pollutants affected rates of illness or death. Joshua Apte is an environmental scientist at the University of Texas at Austin. By looking at life expectancy (预期寿命), his team had hoped to make the threat easier to understand. PM2.5 is what scientists call tiny particles (颗粒) of pollution in the air. Higher levels of PM2.5 can cause health problems and cut months, if not years, from the average length of life. This analysis shows how pollution affects life expectancy in different parts of the world.

    The World Health Organization (WHO) recommends limiting PM2.5 to 10 micrograms per cubic meter of air. Apte's group calculated how holding pollution to this low level would help people. In countries with very dirty air, meeting this standard would lengthen people's lives. However, in countries whose air already meets this standard, the study shows no gain in life expectancy. In other words, meeting the WHO standard won't reduce health costs resulting from dirty air because even below 10 micrograms per cubic meter, pollution still causes serious risks. Meanwhile, the scientists compared how other threats including smoking and cancer shorten the length of life across the globe.

I'm a standup comic. One day, a woman from The Daily News called and said she wanted to do an article on me. When she had finished interviewing me for the article, she asked, "What are you planning to do next?" Well, at the time, there was absolutely nothing I was planning on doing next, so I asked her what she meant, pausing for a moment. She told me she was interested in me! So I thought I'd better tell her something. What came out was, "I'm thinking about breaking the Guinness Book of World Records for Fastest-Talking Female."

The newspaper article came out the next day, and the writer had included my parting remarks about trying to break the world's Fastest-Talking Female record. At about 5: 00 p.m. that afternoon I got a call from Larry King Live, which I had never heard of, asking me to go on the show. They wanted me to try to break the record, and they told me they would pick me up at 8: 00—because they wanted me to do it that night!

Then I sat down to figure out what on earth I was going to do on the show. I called Guinness to find out how to break a fast-talking record. They told me I would have to recite something either Shakespeare or the Bible. Shakespeare and I had never really gotten along, so 1 figured the Bible was my only hope. I began practicing and practicing, over and over again. I was both nervous and excited at the same time.

Then I decided just to give it my best shot, and I did. I broke the record, becoming the World's Fastest-talking Female by speaking 585 words in one minute in front of a national television audience. I broke it again two years later, with 603 words in a minute. My career took off.

People often ask me how I did that. I tell them I live my life by this simple philosophy: I always say yes first; then I ask, "Now, what do I have to do to accomplish that?" Then I ask myself, "What is the worst thing that can happen if I don't succeed? The answer is, I simply don't succeed! And what's the best thing that can happen? I succeed!

What more can life ask of you? Be yourself, and have a good time!
