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.

    What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any especially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

    Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.

    Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

    A few years ago, bubble tea(奶茶) exploded as a popular drink for Internet foodies(吃货) everywhere. Many take this Taiwanese drink as a guilt-free snack similar to juice or a cup of coffee. After all, it has the word "tea" in it, so it has to be healthy…right?

    Not quite. Like coffee, bubble tea's ingredients(成分，配料) might not be so bad on their own, but when they're loaded with sweetener(甜味剂) and artificial flavor(人工香料), they lose their nutritional (营养的) value fast.

    It all starts with those "bubbles" found at the bottom of your drink, which are actually round pieces of tapioca(木薯淀粉). Called "tapioca pearls(珍珠)," they're actually made from a vegetable that grows in South America. And as it turns out, those little balls are loaded with sugar—and not the nutritious, fiber-rich(富含纤维) kinds found in whole grains(全麦类), either.

Cooking tapioca pearls only makes it worse. They're typically fried in hot water, along with even more added sugar, for up to three hours. By that point, these balls could have nearly 160 calories per ¼ cup.

    And don't even get us started on what comes in the extra syrups(糖浆). Thanks to all those processed(加工的) ingredients, the average bubble tea can easily reach 300 to 400 calories per cup!

    On top of being an unhealthy habit, bubble tea could even shorten your life. In 2012, a group of German researchers from the University Hospital Aachen reportedly found aspolychlorinated biphenyls, or PCBs, in tapioca ball samples. These cancer-causing chemicals have also been shown to have other bad effects on the immune(免疫), reproductive(生殖), and nervous systems.

    You might want to lay off your bubble tea addiction. Thankfully, we have a few choices for low-calorie, healthier drinks, instead.

    Amsterdam is a special city. There are many places you should not miss during your visit. Here is our list of the best.

    Amsterdam canal ring

    The city old centre is formed from canal rings, which give you the feeling of space, freedom and peace. Walk through these canal streets or better—take a trip by renting a boat yourself. Another way to explore the Venice of the North is to take a ride on a bicycle. Any way you decide for - enjoy this city.

    The National Maritime Museum

    The Maritime Museum is an attractive place to visit, especially with children. With many attractions in it, this colourful and enjoyable museum will help you understand the history of the Netherlands—a small nation which was one of the world's greatest sea powers.

Amsterdam Brown Cafe

    When you enter Amsterdam old cafes called Brown, at first it will seem too much from the past and too crowded, but the atmosphere is unique. Relax and watch - most of people around will be locals. Feel like one of them—the real Amsterdammers.

    Civic Guards Gallery

    This gallery is filled with old paintings from the Dutch Golden Age. The exhibited canvas may be not always the masterpieces of art, but these group portraits of Amsterdam citizens and their wives are an exquisite (精致的) document of the Dutch civilization and culture centuries ago.

    To avoid waiting lines we advise you to buy your tickets in advance online through our Amsterdam attractions and museums tickets webpage.

    How a few members of the animal kingdom handle the transition to adulthood?

    African elephants

These beautiful beasts come close to imitate teen rebellion. Calves spend a decade with their mothers in female-dominated groups —- and ladies stay there —- but adolescent boys leave mom for noisy crews of bros. In their 20s, they often downsize to smaller male groups.

    Orangutans (猩猩)

Slow metabolism allows these primates to survive food shortages —- times when weather makes ripe fruit scarce. But energy efficiency comes at a cost; growth and maturation take time. Orangutan mamas nurse their young longer than any other wild creature does.

    Orcas(逆戟鲸)

    Killer whales join their mother's familial group for life. This lasting-relationship seems to increase a pup's chance of survival; if mom dies  a young male (under 30) is three times more likely to die than a peer whose mother is alive. Risk of death post-mom-mortem rises as kids get older.

Harp seals

A harp seal's "childhood" lasts just 12 days. A pup's sole purpose during that brief period of coddling(宠爱) is to constantly nurse, gaining a fifth of its birth weight in blubber(鲸脂) every day. Once it's fat —- they become greater from 25 to 80 pounds —- it slides off the ice and takes on the sea.

    Wolf spiders

    Every parent knows that tired toddlers love to hitch a piggyback ride. The wolf spider straps all her babies (40 or 50, on average) onto her back at once, carrying the brood until they are capable of fully functional spider-hood. But luckily she only has to pull them for a few days.

    I had a lot of teachers that I loved. However, the teacher that I remember most was Mrs Green from Marianna, Florida. She was my 5th grade teacher. Since I was a new student, not only in her class, but at the school, she made my time there much more pleasant. I immediately began to like her. She was really funny and I knew that she liked me. She made learning fun. I remember one day for Christmas holidays, she taught us how to make ornaments (装饰物) from eggs. My parents still have some of the ornaments I made.

    She made me leader for many group projects and that made me feel special. I think that would make any child feel special, especially when a child is in a new place with no friends. She made me want to be like that. Not to pick a "favourite" student, but to make every student feel that they are special. That year, I received the Presidential Academic Award (美国总统学术奖). I was really proud and so were my parents.

    Looking back at it, I think the reason why I did so well was that I felt important. Students do better when they feel like they are important or loved. Mrs Green always gets to know her students and forms personal relationships with them, which I will try to do some day. I just hope that there will be a student who finds me to their favourite teacher as I found her to be mine.
