Reflecting(回忆) on the past about those decisions or actions that can't be reversed(推翻) and being occupied with thoughts of “What if?” is no way to live. But there are a few things in life I'd probably do differently if I had the chance.

    I once majored in architecture — something I had been crazy about for as long as I could remember — and then I suddenly had a change of heart. I made an appointment with my adviser, and told him I was no longer certain I wanted to pursue a career in architecture.

    “Don't give up on your childhood dream!” “He's right,” I thought. “I should just stick it out and I shouldn't disappoint the little girl who once loved architecture.”

    It was awful. I was agonized, holding on to a childhood dream that had long since faded. When I talked with a friend about it a year later, he asked: “Right now, what do you want to do with your life?” That's when I came to the realization that dreams change over time and that you should give up the childhood dream if it's not what you want as an adult. Luckily, it wasn't too late. After some serious thought, I changed my major to journalism. It wasn't something I had always imagined myself pursuing — but at that moment,  it was what I wanted.

    We grow up, and sometimes our dreams change — and that's perfectly OK. You just need to ask yourself every once in a while, “Is this still what I want?” If the answer is no, move on and start chasing a new one.

    Are you looking for some new and exciting places to take your kids to? Try some of these places.

    Visit art museums. They offer a variety of activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling exhibits, book signings(签名) by children's favorite writers, and even musical performances and other arts.

    Head to a natural history museum. This is where kids can discover the past from dinosaur(恐龙) models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.

    Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet(木偶) making and stage make-up are just a couple of the special offerings you might find.

    Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.

    Electric Shock

    Injuries caused by electric shock are fairly common. When a person has received an electric shock, no one should go near him/her until the current has been turned off.

    If a shock occurring at work or at home causes someone to lose consciousness（知觉）, electrical connection must be broken before anyone tries to give assistance. You should either turn off the switch at the mains or, if that is not possible, push the person away with a dry piece of wood.

    Treatment of Shock

    Look out for signs of shock. People who have been injured or who may have lost a lot of blood, or those who have had heart attacks, may be in deep shock. The signs to look for are faintness, paleness, a moist, sticky skin, shallow, rapid breathing and a fast but weak heartbeat.

    Shock can prove fatal, and it is essential to do something to prevent its developing. The best way to treat or prevent shock is to keep the patient lying down , better with the legs higher than the head; if possible, raise the lower part of the body on a rolled-up packet or similar object. Make the patient as comfortable as possible, loosening any tight clothing, and comfort him/her because fright increases the effects of shock.

    In 2013, Gabby Frost founded Buddy Project when she was 15. At that time her best friend had been diagnosed(诊断)with a mental health condition, and that was the first time she was made aware of what mental illness was. She wanted to learn more and develop a good support system for her.

    Mental illness affects tens of millions of people in the United States each year, yet only half receive treatment, according to the National Institutes of Mental Health. Buddy Project's website says the service is not a substitute for therapy( 治疗)or other types of mental health care, and it directs people to resources for further help.

    Since founding the organization as a high school student, Frost has helped more than 200, 000 participants find a new friend. On the day when Buddy Project was launched, she used her powerful social media presence to attract nearly 3, 000 participants. "This was around the time when teens really began talking about mental health and found a supportive community online to talk about it,"she said.

    One of the biggest social barriers she had to jump over was that people didn't view her seriously because she was a 15-year-old girl, and even now, she's still a young woman. "Sometimes it's frustrating because people don't think what I do is needed or they don't think I'm professional" she said. "Most people are blown away that a 20-year-old girl is running this and that it's one person doing this but not a whole team. I'm just lucky that I've found a support system that has been able to help my mom and me with the project.

    Your next car could have two seats, three wheels two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car named the Elio. Its two seats sit front and back instead of side by side. The driver is positioned in (he center with the passenger directly behind.

    The starting price for the car is just ＄6.800. It has only one door, on the left side, which cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It has air conditioning, power windows and door locks and an AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

    Paul Elio dreamed as a kid that he would one day own a car company called Elio Motora. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way. Equally important to him was creating US manufacturing jobs and making the car inexpensive enough to attract buyers who might otherwise be stuck in their old, unreliable cars. "Whatever matters to you, this can move the needle on," he said.

    Already, more than 27,000 people have reserved one. Paul hopes to make 250,000 cars a year by 2020. So far, reservation holders are those who will use the Elio as a second or third car for work. Paul Elio believes the car will interest college students as well as used-car drivers who want something newer and more reliable, though.

    I was so fortunate today to be able to offer my love and help to an older lady at my local supermarket. I saw her standing there. I felt quite strange about such a situation.

    What was she looking at? As I looked, I found it was a "Shredded Pork Bun Meal Kit", which is a service that sends customers food ingredients and recipes for them to prepare their own fresh meals. "That's new," I thought. Then I watched as the lady began to dig into her handbag and tried to pull out one of the biggest magnifying glasses (放大镜) I had never seen in my whole life! "Oh, she can't read it," I realized.

    So I stood there and continued watching her. The voice in my mind often asks me to do the right thing. It told me to help her. But I argued back saying, "No. I won't offer help. It will only embarrass her and she is OK now anyway. She has the world's biggest magnifying glass to help her！"

    And I stood there longer. But the voice came back, "Help her, Nicole. Don't be embarrassed. Just do it. Offer your help." So I did it. I read and explained all the things that were included in that box. I read out the ingredients, the instructions on how to cook it and so on.

    She didn't end up buying it, but she was still quite grateful. I walked away knowing that I had helped her and made the right choice. Mostly, I had reminded her that people in this world still care about the old.

    She was seen. She was loved. And she mattered so much that a complete stranger took time to help her. And that stranger was me, a person who argued and didn't want to do so in the beginning.

    So grateful I am when I choose to listen to the voice in my heart. It is because of love. Love is all that ever really matters. I also get happiness through helping her.
