At any discussion of a job offer, money can be a deal breaker. Negotiating an attractive deal, however, can be hard for many job candidates because they lack the necessary skills or simply because they're too concerned that pushing for a high salary can cost them the job.

    These factors certainly can be hurdles (障碍), but it doesn't mean that you give up trying to get the best deal you can get. Needless to say, if money isn't a big factor in your decision, you still need to make sure that the deal you're accepting is fair compared to what's offered in the market. Selling yourself short once can impact your future salaries and set you back financially.

    Here are common mistakes that many jobseekers commit in negotiating money.

    Negotiate too early. Timing is of essence in any negotiation, and negotiating a salary too early in the process can cost you dearly. Many employers, in fact, rank this as one of the biggest mistakes job candidates make. The best timing to begin a salary discussion is after you and your future employer are nearly sure that you've been selected for the position.

    Abandon professionalism. It's common that people, after going through a long recruitment process, can be shocked that the salary offered is significantly below their expectations. If you find yourself in this situation, don't abandon your professional attitude or throw a fit. This likely will get you nowhere except the door.

    There're two options to this situation: the first is that the employer is inflexible (不灵活的) about the budget, and in this case, you may just leave and make a graceful exit from the hiring process.

    The second option is that there's some negotiation room for the hiring manager with other decision makers in the organization. If this is the case, you may be surprised that a final push with a positive attitude and a well-delivered presentation about your skills and market price can get you closer to your expected salary. Still, if this is not acceptable, you don't have to take it.

    Some of the best research on daily experience is rooted in rates of positive and negative interactions, which has proved that being blindly positive or negative can cause others to be frustrated or annoyed or to simply tune out.

    Over the last two decades, scientists have made remarkable predictions simply by watching people interact with one another and then scoring the conversations based on the rate of positive and negative interactions. Researchers have used the findings to predict everything from the likelihood that a couple will divorce to the chances of a work team with high customer satisfaction and productivity levels.

    More recent research helps explain why these brief exchanges matter so much. When you experience negative emotions as a result of criticism or rejection, for example, your body produces higher levels of the stress hormone, which shuts down much of your thinking and activates (激活) conflict and defense mechanisms (机制). You assume that situations are worse than they actually are.

    When you experience a positive interaction, it activates a very different response. Positive exchanges increase your body's production of oxytocin, a feel-good that increases your ability to communicate with, cooperate with and trust others. But the effects of a positive occurrence are less dramatic and lasting than they are for a negative one.

    We need at least three to five positive interactions to outweigh every one negative exchange. Bad moments simply outweigh good ones. Whether you're having a conversation, keep this simple short cut in mind: At least 80 percent of your conversations should be focused on what's going right.

    Workplaces, for example, often see this. During performance reviews, managers routinely spend 80 percent of their time on weaknesses and “areas for improvement”. They spend roughly 20 percent of the time on strengths and positive aspects. Any time you have discussions with a person or group, spend the vast majority of the time talking about what is working, and use the remaining time to address weaknesses.

    First, I want to tell you how proud we are. Getting into Columbia shows what a great well-rounded student you are. Your academic, artistic, and social skills have truly blossomed（开花）in the last few years. You have become a talented and accomplished young woman. You should be as proud of yourself as we are.

    College will be the most important years in your life. It is in college that you will truly discover what learning is about. I want to tell you: “education is what you have left after all that is taught is forgotten”. What I mean by that is the materials taught isn't as important as you gaining the ability to learn a new subject, and the ability to analyze a new problem. That is really what learning in college is about—this will be the period where you go from teacher-taught to master-inspired, after which you must become self-learner.

    Follow your passion in college. Take courses you think you will enjoy. Steve Jobs says when you are in college, your passion will create many dots, and later in your life you will connect them. In his great speech given at Stanford, he gave the great example where he took calligraphy（书法）, and a decade later, it became the basis of the beautiful letters in Microsoft Word. So don't worry too much about what job you will have, and don't be too utilitarian（功利的）, and if you like Japanese or Korean, go for it! Enjoy picking your dots, and be assured one day you will find your calling, and connect a beautiful curve through the dots.

    Most importantly, make friends and be happy. College friends are often the best in life, because during college you are closer to them physically than to your mom and I. Pick a few friends and become really close to them-pick the ones who are honest and sincere to you. Don't worry about their hobbies, grades, looks, or even personalities. You have developed some real friendships in high school in your last two years, so trust your instinct, and make new friends.

    College is the four years where you have the greatest amount of free time, the first chance to be independent, the most possibilities to change and the lowest risk for making mistakes. So please treasure your college years! May Columbia become the happiest four years in your life, and may you blossom into just what you dream to be.

    If you like texting and are trying to lose weight, a new study found that using texting to track(追踪) diet and exercise habits may help you lose weight.

    Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are trying to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.

    Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.

    The study included 26 obese women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (回复) and tips.

    Every morning, the women received a text from an automated(自动的)system that said, "Please text yesterday's personal information of steps you walked and how many sugary drinks you had." Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.

    After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.

    "Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior," Dori Steinberg, who was responsible for this research, said.

    Steinberg said, "Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cellphone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time."

    Two Chinese sisters have landed a dream trip to Buckingham Palace and the Peppa Pig World theme park in the UK. Lately, their mother helped them express their wish online to meet Queen Elizabeth II, which not only caught millions of social media users' attention but also the attention of the British ambassador (大使) to China.

    Five-year-old twins Mi Ai and Mi Ni, who live in Beijing, appeared in a video on social media platform Weibo last week, where they spoke of their love of British cartoon Peppa Pig and their keen interest to visit the Buckingham Palace. Mi Ni said she and her sister wanted to visit the gardens at Buckingham Palace, just like Peppa Pig and her friends did in the cartoon program.

    The British Ambassador answered their call with her own video, inviting the twins to her house in Beijing. "Hello Mi Ni and Mi Ai," she said. "I'm the British ambassador. I'd like you to come and visit me in my house in Beijing and we can perhaps have tea and cookies in a British style." The twins accepted the ambassador's invitation and joined her for a traditional afternoon tea on Monday, when they ate cake and drew pictures of their favorite characters from Peppa Pig.

    The ambassador has made arrangements for the girls and their parents to tour the UK. They are going to tour the studios where Peppa Pig is made, take a trip to Peppa Pig World in Hampshire and visit Buckingham Palace. The queen has not yet said if she will have time to welcome the girls.

    The Peppa Pig series, introduced in the mid-2000s in China, has become extremely popular among Chinese children and adults. As this year is the Year of the Pig according to Chinese tradition, the country has set to mark the Chinese New Year with a film starring Peppa Pig, where audiences can see a number of Chinese cultural elements (元素).
