When you're lying on the white sands of the Mexican Riviera, the stresses of the world seem a million miles away. Hey, stop! This is no vacation-you have to finish something!

    Here lies the problem for the travel writer and critic Edie Jarolim "I always loved traveling and always liked to eat, but it never occurred to me that I could make money doing both of those things," Jarolim said. Now you can read her travel advice everywhere—in Arts and Antiques, in Brides, or in one of her there books, The Complete Idiot's Travel Guide to Mexican Beach Resorts.

    Her job in travel writing began some eight years ago. After getting a PhD in English in Canada, she took a Test.

    Frommer's travel guides, passed it, and got the job. After working at Frommer's, Jarolim worked for a while at Rough Guides in London, then Fodor's, where she fell so in love with a description of the Southwest of the U.S. that she moved there.

    Now as a travel writer, she spends one-third of her year on the road. The rest of the time is spent completing her tasks and writing reviews of restaurants at home in Tucson, Arizona.

    As adventurous as the job sounds, the hard part is fact-checking all the information. Sure, it's great to write about a tourist attraction, but you'd better get the local museum hours correct or you could really ruin someone's vacation.

    Eudaimonia is an Ancient Greek word, particularly stressed by the philosophers Plato and Aristotle, which deserves far more attention than it has because it corrects the shortfalls (缺失)in one of the most central, but troubling words in our modem language: happiness.

    When we nowadays try to clearly express the purpose of our lives，it is the word "happiness" that we commonly turn to. We tell ourselves and others that the most important principle for our jobs, our relationships and the conduct of our day-to-day lives is the pursuit of happiness. It sounds like an innocent enough idea, but too much reliance on the term means that we frequently unfairly tend to quit or, at least, heavily question a great many challenging but worthwhile situations. The Ancient Greeks did not believe that the purpose of life was to be happy; they proposed that it was to achieve Eudaimonia, a word which has been best translated as "fulfilment".

    What distinguishes happiness from fulfilment is pain. It is very possible to be fulfilled and—at the same time—under pressure, suffering physically or mentally, overburdened and, quite frequently, in an irritable (易怒的)mood. This is a slight psychological difference that is hard for the word "happiness" to capture, for it's tricky to speak of being happy yet unhappy, or happy yet suffering. However, such a combination is readily accommodated within the respected and noble-sounding idea of Eudaimonia.

    The word encourages us to trust that many of life's most worthwhile projects will sometimes be in conflict with contentment, and yet will be worth pursuing. Properly exploring our professional talents, managing a household, keeping a relationship going, creating a new business venture or engaging in politics... none of these goals are likely to leave us cheerful and grinning on a daily basis. They will, in fact, involve us in all manner of challenges that will deeply exhaust and weaken us, provoke (激怒)and wound us. And yet we will perhaps, at the end of our lives, still feel that the tasks were worth undertaking. Through them, we'll have achieved something deeper and more interesting than happiness.

    With the word Eudaimonia in mind, we can stop imagining that we are aiming for a pain-free existence—and then blaming ourselves unfairly for being in a bad mood. We'll know that we are trying to do something far more important than smile all the time: we're striving to do justice to our full human potential.

    Finding a friend doesn't seem like a difficult job. However, bad friends are easier to find than good friends these days. If you're sitting there and wondering if you have a bad friend, let me define it for you.

    A bad friend is someone whose jealousies and insecurities outweigh their love for someone. They might want to be a good friend but they're too messed up in their own head to ever actually do it. They wonder if their friends are going out without them or if they're being forgotten and left behind. People who are violently insecure don't have what it takes to be the quality of a friend.

    Bad friends are narcissistic(自恋的). They look for any opportunity to bring the conversation back to them. Worse, they might not even be aware that they're doing it. In their mind, they might think they are the best friend ever, which is truly frightening.

    Bad friends are quick-change. They're by your side when you're fun and you have something to give them but as soon as you're going through a difficult time, they will become indifferent quickly. They won't bring you cold medicine. They won't give you a ride to the doctor, everything they do is self-serving.

    If you find a friend who has these same characteristics, send them to your bad friend list immediately. Your friends are supposed to be the solution to your problems, not the source.

    I believe your twenties are a time when you need positive and helpful friends. In such a time, friendships aren't easy to maintain like they once were in school. Now we actually have to put work into it, we have to make a conscious effort to keep the friendship going. You need to ask yourself, "Is this person worth it? Do they treat me like a fool or what?" if you have doubts, try to make them clear by considering the past experiences. Toxic(有毒的) friendships do nothing but drag you down. My point is that you have to take care of yourself and stop getting in touch with your bad friends. Only surround yourself with people who bring out the best qualities in you. It may sound cruel but it's true.

    A great number of species make their home in the vast waters of the Atlantic Ocean. Although the entire ocean makes up an ecosystem, many smaller habitats are found within, including an open-water habitat off the coast of the Northern Atlantic Ocean known as the Sargasso Sea. Sargassum is an alga(海藻) that floats in masses that can continue for miles. The waters of the Gulf Stream push the water in a northward move into this area. This constant move and varying temperature support the accumulation of the brown-colored seaweed.

    The Sargasso Sea is so enormous that one method of information collection has not been enough for scientists to obtain an accurate picture of what takes place within this ecosystem. Researchers have needed to employ several methods of sampling. Methods such as dragging nets over the surface of the water and videotaping beneath areas of sargassum have served scientists well. Information collected has shown that the Gulf Stream pushes brown algae from open water into the Sargasso Sea area, creating a diverse floating habitat in an area that would otherwise not support that wildlife.

    In the most recent study of the sargassum community off the shores of North Carolina, eighty-one fish species were documented as using the area as a microhabitat. This is an increase from previous studies. The types of fish found here are both commercially and environmentally important. The South Atlantic Fishery Management Council is working to regulate the harvesting of sargassum. The Council hopes to have the area classified as an Essential Fish Habitat. Which would afford it certain protections.

    Further research needs to be done before scientists understand how to best protect the Sargasso Sea as well as understand how it goes about supporting so many important types of wildlife.

The hardest thing about planning a big European vacation is actually narrowing down where to go—there are just so many amazing places. That's why we've put together what we think are the best cities in Europe. 

AMSTERDAM, NETHERLANDS

Amsterdam is the kind of city that you can't help but fall in love with. It's the kind of place where you dream about moving and buying an apartment that overlooks (俯瞰) a peaceful river. It's relaxing and you get a sense that the locals have an amazing quality of free life. We love simply walking around the canals and exploring the city's neighborhoods. 

BERLIN, GERMANY

Berlin is said to be "poor but charming" and we think that's a pretty good description. Actually, Berlin is becoming more expensive as its popularity grows, but it's still the top spot for Germany's artistic scene. Berlin isn't particularly pretty but it's an energetic city with cool people and cooler graffiti-covered (涂鸦) neighborhoods. 

LISBON, PORTUGAL

Lisbon is a hot destination and I doubt it will be quickly moving up in the ranks of Europe's most visited cities. Lisbon is a popular coastal city that's famous for its unique buildings and charming café culture. It's also very friendly on the wallet when compared to other Western European cities—food and lodging are both priced reasonably and attractions are about average. 

FLORENCE, ITALY

Florence may be touristy but that's no reason to ignore this birthplace of the Renaissance (文艺复兴). If you do your research, you can find plenty of excellent Italian restaurants and world-class ice cream. And, of course, the city is beautiful and home to top museums so it's a dream for art and history lovers.

The Stanford marshmallow (棉花糖) test was originally conducted by psychologist Walter Mischel in the late 1960s. Children aged four to six at a nursery school were placed in a room. A single sugary treat, selected by the child, was placed on a table. Each child was told if they waited for 15 minutes before eating the treat, they would be given a second treat. Then they were left alone in the room. Follow-up studies with the children later in life showed a connect ion between an ability to wait long enough to obtain a second treat and various forms of success.

As adults, we face a version(版本) of the marshmallow test every day. We're not tempted (诱惑) by sugary treats, but by our computers, phones, and tablets — all the devices that connect us to the global delivery system for various types of information that do to us what marshmallows do to preschoolers.

We are tempted by sugary treats because our ancestors lived in a calorie-poor world, and our brains developed a response mechanism(机制) to these treats that reflected their value — a feeling of reward and satisfaction. But as we've reshaped the world around us, dramatically reducing the cost and effort involved in obtaining (获取) calories, we still have the same brains we had thousands of years ago, and this mismatch(不匹配) is at the heart of why so many of us struggle to resist (抵抗) tempting foods that we know we shouldn't eat.

A similar process is at work in our response to information. Our formative (有重大影响的) environment as a species was information-poor, so our brains developed a mechanism that prized (高度重视) new information. But global connectivity has greatly changed our information environment. We are now endlessly bombarded (轰炸) with new information. Therefore, just as we need to be more thoughtful (深思熟虑的) about our caloric consumption (热量消耗), we also need to be more thoughtful about our information consumption, resisting the temptation of the mental "junk food" in order to manage our time most effectively.
