Mary Krupa became friends with the grey squirrels during her first week at Penn State,after spotting them running around and idly（漫不经地）wondering what they would look like with tiny hats on their heads.Today, everyone at the university knows her as the "Squirrel Girl".

    Mary started bringing them food,and gradually they began to trust her.She managed to put a hat on a squirrel and take a picture.Thinking that her colleagues could do with something to lift up their spirits,she started posting similar Photos on Facebook.The response Was greatly positive,and before long Mary and her squirrels became an Internet sensation.

    Growing up in a neighborhood outside State College,Mary was always fond of birds and animals around her home,but she didn't interact with people very much.She was later diagnosed with Asperger's syndrome,but the squirrels changed that.The squirrels are actually a good way to break the ice,because I'll be sitting here patting a squirrel and other people will come over and well just start like feeding the squirrels together and chatting about them,"she said."I am a lot more outgoing.

    And in case you're wondering how Mary is able to get the squirrels to do what she wants for her photos,it has a lot to do with food.For example,whenever she wants them to hold or play with something,she puts peanut butter on the prop（道具）,and they'll grab it.But getting to that part took a while.In the beginning,she would throw peanuts up the trees on campus and invite the squirrels to come down and get them,but they hesitated to approach her.She had the patience to earn their trust,though.

    This year,Mary is graduating with a degree in English and wildlife sciences.She wants to be a science writer and educate people on how to preserve the environment.As for her furry friends,Mary plans to stay in the area and visit them as often as she can.

    The first time she saw Bryce Loski, she flipped. The first time he saw Juli Baker, he ran. For six years of living close by, they had played the same game of cat-and-mouse (Juli was the cat; Bryce was the unfortunate mouse).

    For years Juli dreamed of one thing: her first kiss from the boy. Nothing else seemed to matter. But when Juli's favorite sycamore tree is threatened by developers, things begin to change. She begins to see things and places and people in a different light. Things, for years, she thought to be important, become things she can live without; and people she thought to be the center of her universe, become nothing more than a star in a faraway galaxy.

    Things begin changing with Bryce also. It all begins with the eggs…which then cause a domino effect of changes with his relationships with his best friend, his father, the Bakers and, ultimately, Juli.

    I had seen this book on the shelf at bookstores for years, but never bothered to pick it up because it looked to be another book from Jerry Spinelli (not exactly my favorite author in the world) and so, continually, I would walk past it without giving it a second glance. If by chance I had picked it up, I most likely would not have read it, since the summary on the back didn't seem too appealing. It wasn't until a couple of weeks ago that I heard about Flipped the movie. I read an interview with Callan McAuliffe (the actor who portrays Bryce) and thought that Flipped was a romance right up my alley; cute, innocent and as far from Jane Austin as you could get. After reading the interview and a summary of the movie, I found the plot-line to be somewhat appealing and a definite breath of fresh air opposed to the dark material I have been recently reading and writing. I found the book a few days later in a Goodwill bookstore and finished it in three days.

    The story isn't what you would consider deep…it isn't shallow and pointless either…I guess you could say it's the perfect balance of life-lessons and innocence.

    You read about Bryce and Juli (each from their own points of view) and how, throughout six years, their lives and views and opinions change and develop. Flipped is somewhat of a coming of age story about two kids learning to see life from the other's point of view and learning that growing up isn't about staying the same, but changing; changing likes and dislikes; changing friends and crushes and views on family.

Uniquely written, every other chapter showing the same scenes and events, only from the other's point of view, you see how the saying, "Two sides to every story," is true. You are able to see both Juli and Bryce's reasons for doing what they do and saying what they say…not just what the other sees.

    It will be interesting to see how this writing style comes into play in the movie. Overall I thought this story was incredibly cute and light-hearted, although it didn't entirely meet my expectations. Especially the ending. I felt as though it ended quite abruptly and that there was more story that needed to be told.

    But even with that, after having taken a step back and taken my mind off of Flipped, I find the story has stuck with me and stayed in the back of my mind, making me highly anticipate seeing this book turned to a film. I understand why it has been so popular for almost two decades and am looking forward to seeing Flipped on the big screen soon.

    These days, it seems that almost all of us are too serious. My older daughter often says to me, "Daddy, you've got that serious look again." Even those of us who are committed to non-seriousness are probably too serious. People are frustrated and anxious about almost everything—being five minutes late, witnessing someone look at us wrong or say the wrong thing, paying bills, waiting in line, overcooking a meal, making an honest mistake -- you name it, and we all lose perspective（理性判断）over it.

    The root of being anxious is our unwillingness to accept life as being different, in any way, from our expectation. Very simply, we want things to be a certain way but they're not a certain way. Life is simply as it is. Perhaps Benjamin Franklin said it best: "Our limited perspective, our hopes and fears become our measure of life, and when circumstances don't fit our ideas, they become our difficulties." We spend our lives wanting things, people, and events to be just as we want them to be—and when they're not, we fight and we suffer.

    The first step in recovering from over-seriousness is to admit that you have a problem. You have to want to change, to become more easygoing. You have to see that your own anxiety is largely of your own creation—it's made up of the way you have set up your life and the way you react to it.

    The next step is to understand the link between your expectations and your frustration level. Whenever you expect something to be a certain way and it isn't, you're upset and you suffer. On the other hand, when you let go of your expectations, when you accept life as it is, you're free.

    A good exercise is to try to approach a single day without expectation. Don't expect people to be friendly. When they're not, you won't be surprised or bothered; if they are, you'll be delighted. Don't expect your day to be problem-free. Instead, as problems come up, say to yourself, "Ah, another barrier to overcome." As you approach your day in this manner you'll notice how elegant life can be. Rather than fighting against life, you'll be dancing with it. Pretty soon, with practice, you'll lighten up your entire life. And when you lighten up, life is a lot more fun.

    In this Pennsylvania city, Pittsburgh is shrinking but getting wealthier. Since 2000, its population has declined by 95,000 while its income per capita (人均) has shot up 24 percent. The trend is taking hold in many other cities, like Buffalo in New York, Providence in Rhode Island and New Orleans.

    Some of these areas have created more high-paying jobs in energy, health care or education. Others have managed to reshape their producing industry for a new economy. Higher-paying jobs have a greater effect because they create demand for additional services. "The story in Pittsburgh is very positive, and other areas are looking at it as an example of the transformation that might be possible,” said Guhan Venkatu, who wrote an economic history of the area called “Rust and Renewal” for the Federal Reserve Bank of Cleveland.

    Carnegie Mellon University and the University of Pittsburgh have helped bring tech jobs and innovation(革新) to the area by sponsoring tech centers that help graduates start companies without moving to Silicon Valley or San Francisco. This has helped keep Pittsburgh's educated young population growing even as the entire population in the city has dropped.

    Pittsburgh has more STEM (science, technology, engineering and math) jobs than other shrinking cities, about 80, 000 or 7% of all jobs. STEM jobs add productivity and income growth to the area. Manufacturers of high-tech medical equipment in the Pittsburgh area also have doubled employment in the last 10 years.

    However, some experts question whether growing income per capita can really make up for a declining population. According to Patrick Adler, a researcher at the University of Toronto, population loss does matter if it means lower-skilled workers have fled because of a lack of opportunity. What's more, high-paying jobs in education and health care can disappear if the population declines too greatly. So it'd be wise to find ways to increase the population.

    About a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear this was a business call. "I want to apply to work with you at Facebook," she said. "Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?"

    My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook's needs front and center. It was a killer approach. I responded, "Recruiting is my biggest problem. And, yes, you can solve it."

    Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.

    The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: "Careers are a jungle gym, not a ladder."

    As Lori describes it, there's only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.

When we meet someone for the first time, we usually get a vague sense of what kind of person they are by the way they shake hands, talk, or walk. In the age of social networking, however, first impressions are sometimes made even before we actually meet someone in person—that is, by looking at their profile photo.

    According to a recent study, these social images say a lot about our personality. In the study, presented in a paper at the International AAAI Conference on Web and Social Media, a group of researchers from the University of Pennsylvania in the US used software to analyze the profile pictures of 66,000 users of US social platform Twitter and 3,200 of their tweets. At the same time, about 434 participants were asked to complete a survey about their personality type. The researchers wanted to find out if there was a connection between personality traits—like openness, extroversion, and neuroticism(神经质)—and a person's profile picture.

    According to the results, open people are more likely to pose in an unusual way and use objects such as glasses or a guitar in their profile photo because they enjoy new and exciting experiences. Meanwhile, neurotic people often hold back their negative emotions. They try to avoid showing their face；Instead, they use an image of something like a pet, a car or a building.

    Apart from the objects in profile pictures, the colors used in them also give us some hints about the photo's owner. For example, extraverts were found to have the most colorful profile images, as they want to emphasize their personality and show themselves off, the researchers wrote.

    Although social media photos "usually represent an extension of one's self, they also allow a user to shape his or her own personality and idealized view," according to the researchers. So, when choosing a profile photo, maybe we should ask ourselves first what kind of image we'd like to convey. After all, first impressions always last.
