The most important lessons in life that we need to learn are the results of our poor decisions. Although time and experience are the best teachers, we also suffer from experiences such as our sacrifices, suffering and the hardships. Good judgment develops only when we truly learn from our mistakes. However, many people keep repeating the same mistakes before learning their lessons because as they say, they are just humans who are subject to making mistakes.

Our weaknesses in life can be turned into our strengths if we immediately acknowledge and recognize the fact that we mess up and learn from them. Our good or bad experiences help us learn better judgment in life. Yet, too many people are in denial and place the blame on others without realizing that the minute they take responsibility for their action is when the learning process begins. Apart from learning from our own experience, we can also learn valuable lessons from the experience of others. It allows us to observe our behavior from another angle. When we recognize our mistakes and prevent them from happening again, we are, therefore, learning.

    Quickly identifying our mistakes and changing behavior accordingly requires less time and energy than denying mistakes. However, acknowledgement of mistakes requires belief in the idea that the perfection is not possible.

    It is easier to analyze our mistakes especially when we talk to others, which can help people to sort out comments or criticisms after a mistake is made. Despite our tendency to avoid mistakes, timely acknowledgement is one of the best ways to prevent them from repeating.

    You may think, salt is just a simple cooking element we shake on our food for a little extra taste. But salt is much more than that. Without salt our muscles would not move. Our nervous systems would not operate. Our hearts would not beat.

    But do not think rubbing salt into a wound will help. Doing that would be painful and not heal the wound. “To rub salt into a wound” is an idiom that means to purposefully make a bad situation worse.

    Early humans got the salt they needed to stay alive from the animals they killed. But advances in agriculture led to a diet low in salt. So, humans needed to find other sources. Those who lived near the ocean or other natural sources for salt were lucky. Those who did not had to trade for salt. In fact, people used salt as a method of payment in many parts of the ancient world. The word “salary” comes from the word “salt”.

    Salt also played an important part in population movement and world exploration. Explorers understood that if they could keep food fresh, they could travel longer distances. So they used salt to preserve food and explore the world.

    Salt was so important that, according to food historians, it was traded pound-for-pound for gold. Today, people still use the expressions “worth one's salt” or “worth one's weight in salt”. The expressions describe a person of value.

    A person might also be called “salt of the earth”. That description means he or she is dependable and trustworthy. However, when you say “I think we should take what he said with a grain of salt”you mean you accept it but maintain a degree of doubt about its truth.

    It's been said that honesty is the best policy．It sounds like the simplest thing in the world，but being truly honest with others and with yourself can be a real challenge．Most of us learned to be dishonest as children．Remember that dishonesty is rooted in fear，so you must look for and face those fears．By listing areas where you have a problem，and then working to deal with them，you can battle these habits．If you find yourself lying because you fear disapproval from someone，for example，perhaps you need to learn how to stop being a people pleaser and be yourself．Most importantly，admit your errors so that you can forgive yourself and use those experiences to reinforce your determination to do better．

    If you feel guilty for having been dishonest in the past，apologize to the person you lied to or find a creative way to make things right．If you've lied to a person who plays an important role in your life （a significant other，relative，or friend），the best （but most difficult） thing to do is to come clean．

    Think honestly．This may sound silly，but if you don't think honestly，you won't be honest．

    If you're pushed into a corner and don't know how to respond，you have the right to remain silent or say"Can we talk about this another time?"or"I really don't feel comfortable talking about this．"Don't say"I don't know．"

    Practice being honest on the simple things．Abraham Lincoln became famous for going to great lengths to return a few cents that did not belong to him，hence the nickname"Honest Abe"．By applying honesty to the little things，you will get in the habit of being honest in general．

    Cigarette ends are everywhere — littering our streets and beaches — and for decades they've been thought of as "unrecyclable". But a New Jersey based company, called Terra Cycle, has taken on the challenge, and has come up with a way to recycle millions of cigarette ends and turn them into industrial plastic products. Its aim is to recycle things that people normally consider impossible to reuse.

    Obviously it would be even better for the environment if everyone just stopped smoking, but the statistics show that although there has been an increase in anti-smoking ads and messaging, between 2000 and 2014, global sales of cigarettes increased by 8 percent, and a whole lot of those cigarette ends are ending up as trash. Since most of our litter eventually ends up in waterways, cigarette ends can surely pollute the surrounding environment. "It only takes a single cigarette end to pollute a liter of water," Terra Cycle founder, Tom Szaky, said. "Animals can also mistake littered cigarette ends for food."

    So how do you go about turning all those poisonous ends into something useful? Terra Cycle does this by first breaking them down into separate parts. They mix the remaining materials, such as the tobacco and the paper, with other kinds of rubbish, and use it on non-agricultural land, such as golf courses. The filters(过滤嘴) are a little harder. To recycle these, Terra Cycle first makes them clean and cuts them into small pieces, and then combines them with other recycled materials,  making them into liquid for industrial plastic products.

    They're now also expanding their recycling offerings to the rest of the 80 percent of household waste that currently can't be recycled, such as chocolate packaging, pens, and mobile phones. The goal is to use the latest research to find a way to stop so much waste ending up in landfill(垃圾填埋), and then get companies to provide money for the process. And so far, it's working.

    "We haven't found anything that we can't recycle, "communications director of Terra Cycle, Albe Zakes, said. "But with the amount and variety of packaging and litter in the world, we are always looking for new waste streams to address."

    What's it like to become a music star with millions of fans? These young artists know the feeling. Over the course of their short careers, they have attracted the attention of the biggest stars in the world and taken home prizes from major shows. For now they're just kids that everyone in music is watching. Check out the next generation of stars below.

    FIFTH HARMONY

    The 1990s was a brilliant period for girl groups. But after that few groups have been able to make much of an influence. This doesn't seem to bother Fifth Harmony, who landed the biggest hit of their career in 2016 with "Work from Home", a pop song that encourages everyone to ask for leave more often. When it climbed to No.4 on the Billboard Hot100, it was the first time that a girl group had entered the top 5 in the past ten years.

    LORDE

    It's been four years since the release of Born Heroine — the hot selling CD that made her a 16-year-old global sensation and the spokeswoman for a new generation of smart, strong-minded, creative female pop artists. She contributed to The Hunger Games soundtrack (插曲) in 2014, and for this time setting foot in Hollywood production also brought her more opportunities in her following career.

    TROYE SIVAN

    You might recognize the rising star Troye Sivan from YouTube, where he's been uploading videos since he was 12 and his channel already has millions of fans, or from the movies, where he played the role of young Wolverine in X-Men Origins: Wolverine.

    Addyson Moffitt is an 8-year-old from Kansas City, Missouri. Maurine Ghelagat is a 9-year-old from a village in Kenya called Bartabwa. It might not seem as if the girls have much in common, but when they met at a dinner two years ago, in Kansas City, they immediately hit it off.

    "We had this one little red ball to play with," Addyson told TIME for Kids. "We didn't have any electronics or phones, no iPads or TV. It was just us playing." Addyson and Maurine still keep in touch now.

    The dinner was hosted by the nonprofit group World Vision International, which builds wells, pipelines, and rain catchers in communities where people find it hard to get clean water. Addyson, was at the dinner because her family supports World Vision. Maurine was there because her village had been without clean water. World Vision fixed that by building a water station there.

    "People helped Maurine so she could have clean water, and kids are dying because they don't have it," Addyson says. "I want to help."

    Races are one way World Vision raises money to pay for its water projects. Runners run a race, often a 26-mile marathon or 13-mile half marathon. They ask people to support them by donating(捐赠) to World Vision.

    Addyson decided to run the 2017 Kansas City Half Marathon for World Vision. At age 7, she was one of the youngest-ever runners in the race, and had to get special permission to take part.

    Addyson spent four months training with her parents, waking up before 6 a.m. to run. Meanwhile, she started fundraising(募捐)by asking friends to make donations as birthday presents and clearing tables at a restaurant for tips.

    By October 2017, when Addyson ran the race, she'd raised more than $20,000. She's the youngest person in World Vision history to raise more than $10,000. In 2018, she ran again and raised $36.000.

    But Addyson's work is not finished. "My goal is for every kid to have clean water," she says.
