When I was about 12, I had an enemy, a girl who liked to point out my shortcomings(缺点). Week by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

    He listened to me quietly, then he asked.“Are the things she says true or not? Janet, didn't you ever wonder what you're really like? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

    I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I go to fairly clear picture of myself.

    I brought the list back to Daddy. He refused to take it.“That's just for you，” he said.“You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.

    A long time ago, soldiers fought wars on foot. Then they began to ride horses to battle. Until the invention of the stirrups (马蹬), though, men could not fight well with swords or spears while on horseback.

    Without stirrups, soldiers had no place to put their feet. They could not stand up to use their swords without falling off their horses. They could throw spears only with the force of their arms.

    Using stirrups, a soldier could stand up in his saddle (鞍). He could put a spear under the top part of his arm and charge with the force of his horse. He could use force when fighting with a sword. And he could win most fights against soldiers who did not use stirrups.

    The first stirrups were made in India. Because the weather was warm, people did not wear shoes. The Indian stirrup was made of rope. It fit around the big toes. Later, the Chinese made a foot stirrup of wood. Because the Chinese lived in a colder country, the stirrup had to fit around shoes. Still later, around A. D. 700, soldiers in Asia used strong iron foot stirrups.

    One of the greatest sources of unhappiness, in my experience, is the difficulty we have in accepting things as they are.

    When we see something we don't like, we wish it could be different. We cry out for something better. That may be human nature, or perhaps it's something ingrained(根深蒂固的) in our culture. The root of the unhappiness isn't necessarily that we want things to be different. However, it's that we decided we didn't like it in the first place. We've judged it as bad, rather than saying, "It's not bad or good, and it just is it."

    In one of my books, I said "You should expect people to mess up and expect things to go differently than you planned". Some readers said it's too sorrowful to expect things to go wrong. However, it's only negative if you see it as negative and judge it as bad. Instead, you could accept it as the way the world works and try to understand why that is.

    This can be applied to whatever you do: how other people act at work, how politics works and how depressing the news media can be. Accept these things as they are, and try to understand why they're that way. It will save you a lot of sadness, because you'll no longer say, "Oh. I wish bad things didn't happen!"

    Does it mean you can never change things? Not at all. But change things not because you can't accept things as they are, but because you enjoy the process of changing, learning and growing.

    Can we make this world a better place? You can say that you'll continue to try to do things to help others, to grow as a person, to make a difference in this world. That's the correct path you choose to take, because you enjoy that path. Therefore, when you find yourself judging and wishing for difference, try a different approach: accept, and understand. It might lead to some interesting results.

    The European Parliament has approved a law banning a wide-range of single-use plastic items, such as straws and cotton buds by 2021. "Europe is setting new standards, paving the way(铺路) for the rest of the world," the European Commission's vice-president Frans Timmermans, who is responsible for sustainable development, said in a statement.

    The new plans come after the EC found that plastics make up more than 80% of marine litter, which has disastrous effects on wildlife and habitats. The EU parliament notes that because of its slow rate of breaking down, plastic residue(残余) has been found in marine species as well as fish and shellfish - and therefore also makes its way into the human food chain.

    Under the new European law, tobacco companies will be required to cover the costs for the collection of cigarette butts. Manufacturers of fishing tools will also have to pay for the retrieval(找回) of any plastic nets that have been left at sea. There's also a new focus on further raising public awareness, where producers of items such as tobacco filters(滤嘴), plastic cups, and wet wipes will be required to clearly explain to users how to appropriately dispose of them.

    The European Commission first suggested the ban in May, which was approved by member states in October. China last year banned the import of 24 varieties of solid waste, including types of plastic and unsorted paper, putting pressure on Europe to deal with its own waste.

    The World Economic Forum estimates that there are about 150 million tons of plastic in the world's seas. A study published in Science in 2015 suggested that between 5 and 13 million tons more are flowing into them every year. Research shows there will be more plastic than fish by weight in the world's oceans by 2050, which has encouraged policymakers, individuals and companies into action.

    Kerala, India, has placed a tax on hamburgers, pizza and other fast food. The 14.5 percent tax will be added to foods at restaurants such as McDonald's, Pizza Hut and Burger King.

    The tax is being called a "fat tax" because it adds cost to foods considered high in fat and calories. It is the first fast food tax enacted in India, where obesity levels are rising in the growing middle class.

    Kerala's Finance Minister Thomas Isaac suggested the tax after learning of similar measures in other countries. He hopes it will get people to choose to eat healthy food, which he said is "going out of fashion."

    Dr. Anoop Misra at New Delhi's Fortis Hospital strongly supports the" fat tax" as a way to reduce the number of diabetes cases in young people.

    A government finance official in central Gujarat says that the state is considering a similar 14.5 percent tax." This idea can also be adopted in the state, as we also have high consumption of junk and unhealthy food," the official said.

    Critics of the tax say it probably will not stop people from buying fast food. IT engineer Gaurav Singh wants the government to focus on education and awareness instead of taxing fast food.

    "The one food that is eaten widely in Kerala is the 'paratha', which is basically high in fat, high in refined(精制的)flour, and it is cheap. It can't be taxed because it is highly unorganized."

    Some doctors and health experts say the tax should also include other snack foods and sugary drinks sold across the country.

    One fast food customer In New Dehli, Vijay Deoli believes the government should deal with more important issues. "First you have to clear up the air, the water, etc. This is a small thing."

    Others say the government should do more to bring attention to fast food and obesity rather than changing people's choices.

    Many health experts agree that bringing attention to the issue is important. But Dr. Misra thinks education alone does not work.

    He compared the tax to a law passed several years ago that got people to wear seat belts to avoid paying a fine. "Laws can change people's habits."

    "Smile!" I shouted, holding a yellow sign up on a busy street in Seattle. We were three thousand miles away from home on a Random Acts of Kindness and Volunteerism Road Trip. We had two aims. One was to try out our new "Smile!" signs and see how much kindness and joy we could spread in Pike Place Market. The other was to raise $80 by doing street performances, enough for gas to Portland and a small hotel room.

    We weren't sure how people would react (回应) to our signs. I nervously raised up our signs and shouted, "Hi, there!" to a young couple. They looked over and felt confused. Then they read our signs and broke into a smile. Before long, some tourists wanted to take a photo with us and some strangers stopped to ask us about our signs.

    In fact, we paid so close attention to our "Smile!" project that we forgot the other aim. Before we knew it, the sun was setting, and we had no money for our trip to Portland. We sat down to watch a blind musician play the guitar while thinking about what to do. He was packing up when a passing crowd kicked down his change bowl. He stumbled (绊倒) into the crowd. We rushed to help him, but another man moved more quickly to help him.

    Once the musician had his money safely returned, we ran over to meet the strange helper and said, "We just wanted to praise you for your good deed." He smiled, looking at our signs. "Your trip reminds me of something similar I once did when I was youn," he said. "Look! I'd like to donate (捐赠)." We told him, "No, thanks! We are fine. We've collected plenty of money." We lied. "Please let me donate. It will make me feel like I'm a part of this adventure," he insisted. And then the stranger opened his wallet and pulled out four $20 bills. The money was exactly what we had intended to raise that day. We were astonished. It seemed as if he had known somehow.
