Conor Grennan was unwilling to be a volunteer(志愿者). The 29-year-old American was not sure if he had the skills or a strong feeling for it.However, he went to work at an orphanage(孤儿院) in Nepal. His first thought was to make people impressed.

    "I thought that if I volunteered just once. I could retell the story over and over," Grennan said in a Huffington Post article.However, his three-month stay it the orphanage turned into in unusual experience. It was 2004 and Grennan had given up his job to begin a year-long around-the-world trip, His first three months were spent in Nepal.

    When he arrived in the village, he knew nothing about the children or the local culture. When he opened the gate of the Little Princes Children's Home, he was faced by the excited children.

    The young American ended up caring for 18 children. He later discovered that they were trafficked(被拐卖的)children. So he walked through the mountains with great difficulty to find the kids' families, "I started walking with photos of the kids." he told the Reuters reporter. "I would show up in villages and show photographs around. I went with 24 photos, and I found 24 families." At the same time, he put his heart into Nepalese culture.

    Grennan said, “Volunteering is the single best way to see how the rest of the world lives.”

    He also encouraged others to do what he had done. He believes that volunteering needs only making decisions to show up.

    Grennan's fight against child-trafficking has changed him. His book, Little Prince, came out last week.

Finding the Real You

    Psychometric testing—personality testing—has been very popular nowadays as studies show their results to be three times more accurate in predicting your job performance. These tests are now included in almost all graduate recruitment (招聘) and are widely used in the selection of managers.

    The most popular of these personality tests is the Myers-Briggs Type Indicator (MBTI). It is based on the theory that we are born with a tendency to one personality type which stays more or less fixed throughout life. You answer 88 questions and are then given your “type”, such as Outgoing or Quiet, Feeling or Thinking.

    Critics of personality testing raise doubts about “social engineering”. Psychologist Dr. Colin Gill warns that the “popular” personality traits (特性) have their disadvantages. “People who are extremely open to new experiences can be butterflies, going from one idea to the next without mastering any of them.” However, the psychometric test is here to stay, which may be why a whole sub-industry on cheating personality tests has sprung up. “It's possible to cheat,” admits Gill, “but having to pretend to be the person you are at work will be tiring and unhappy and probably short-lived.”

    So can we change our personality? “Your basic personalities fixed by the time you're 21,”says Gill, “but it can be affected by motivation and intelligence. If you didn't have the personality type to be a doctor but desperately wanted to be one and were intelligent enough to master the skills, you could still go ahead. But trying to go too much against type for too long requires much energy and is actually to be suffered for long. I think it's why we're seeing this trend for downshifting—too many people trying to fit into a type that they aren't really suited for.”

    Our interest in personality now exists in every part of our lives. If you ask an expert for advice on anything, you'll probably be quizzed about your personality. But if personality tests have any value to us, perhaps it is to free us from the idea that all of us are full of potential, and remind us of what we are. As they say in one test when they ask for your age: pick the one you are, not the one you wish you were.

    When was the last time someone unexpectedly did something nice for you? Not someone you knew, but a total stranger? It's happened to me a few times, but two instances really stand out.

    A few years ago, I was dining in a restaurant with a friend who kept talking about himself completely not aware of the fact that I was sitting there in misery. It wasn't my friend's talks that made me suffer. I was recovering from a broken heart, and just sitting down to dinner reminded me of my last relationship. I could have burst into tears right there at the table.

    When we picked up the check, the waitress said “ Your meal was already paid for .” My friend and I didn't have a clue how it happened. Then I remembered a man I saw out of the corner of my eye. He was dressed in mostly white, sat down at the bar, had a beer, and stayed for maybe ten minutes . The waitress said ,”Yes , the gentleman in white paid for you .” It felt like an angel was saying “I see you , honey. It's going to be okay.”

    Just last year, I was running a half-marathon. With just 1 mile to go, I was out of gas. Runners call it “hitting the wall”. I thought I couldn't move another inch. Out of nowhere, a stranger came up to me and said, “What's your name, sweetie? Jennifer? Okay, Jennifer, let's go! Come on! It's just around the corner! You can do it!” And he ran with me until I picked up my pace. I found him at the finish line to thank him for the encouragement only to learn he wasn't even supposed to be in the race that day.

    I still shake my head when I think of these momentary angels that came to me at my point of need. Do you have any experiences like these?

    It was a Saturday morning, a day I believed would end in victory. For weeks, I had been preparing for the match at the county fairgrounds, sponsored(赞助) by our local riding club. My horse, Tonka, and I could run faster than any kid in the county, and I hoped to bring home a blue ribbon.

    My mother usually drove me to the riding events, but on this day, my father planned to drop us off at the fairgrounds with the horse trailer(马车) .

    Although we never discussed it, my father's struggle with alcoholism had become the silent center of our family life. My mother was paralyzed with fear and indecision. Her salary as a part-time nurse couldn't possibly support four children. No one talked about alcoholism in those days, and it was my family secret.

    We climbed on the trailer and my father pulled out of our driveway and headed toward the fairgrounds, picking up speed once we hit the main road. It wasn't until we felt a big bump that I realized the trailer was out of control. The dream of my riding winner disappeared. Tonka lay on the floor, completely still. No words were possible. I knew he was dead.

    Suddenly a man appeared. "Are you all right?" he asked. "Yes." I answered, although I knew that nothing was all right. "Sit here on the grass," he said. He bent down to look into the trailer. Tonka remained still. He touched Tonka and then turned to face me. "He is going to be OK. He has just been knocked unconscious." He rubbed Tonka's cheeks and gently pulling his ears. Tonka rose to his feet.

    Our father was talking to a police officer. He was upset and in pain and took little notice of me. I looked back; the man was gone.

    I never forgot him. He gave me strength and a sense of hope in a dark and frightening moment.

    You can see a sea turtle named Herman, an octopus ( 章鱼) called Octavia, and a seal named Lidia at the Smithsonian's National Zoo in Washington, D.C. Rather than real animals, they are actually artworks made out of plastic trash from the ocean.

    These artworks are part of a traveling exhibit called "Washed Ashore: Art to Save the Sea". The Washed Ashore project, led by the artist called Pozzi, works to raise awareness about plastic pollution in Earth's oceans.

    More than 315 billion pounds of plastic litter the world's oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches. Rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces.

    Thousands of sea animals die each year from eating plastic bags and other things. Each year, millions more pounds of plastic end up in the ocean. A recent study found that if that continues, by 2050 the total weight of plastic will be more than that of all the fish in the ocean.

    The Washed Ashore project is working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 300 miles of beaches. They helped Pozzi create more than 60 artworks of sea creatures harmed by plastic pollution.

    "These artworks are a powerful reminder of our personal role and global responsibility in preserving biodiversity (生物多样性) on land and in the sea," says Dennis Kelly, director of the National Zoo.

    Knowing what to do at checkout and properly preparing for it can turn a potentially heated situation into a quick thank you add goodbye. Below we made a list of five things you should remember at hotel checkout.

Don't be late to check

    Hotels may add an extremely high price for being just a half hour late. If you know you won't make the cutoff time, it never hurts to call ahead and try to negotiate away a potential charge.

    Don't forget to double cheek the room and safe

    Make sure you don't leave things behind. If you have an early flight or checkout time, pack up as much as you can the night before so that last-minute rush isn't too annoying. Also, be sure to take out anything in the room safe.

    Don't forget to tip the housekeepers

    It's always polite to leave some money for the people keeping your room clean.

    Don't ignore the detailed bill

    You may be in a rush, but give the detailed hill a careful look to see if the hotel charge is different from the rate you initially booked.

    Don't get angry

    Shooting at the assistant manager standing behind the front desk probably won't help.

    When dealing with an unexpected item on the bill. Think about how difficult it can be to deal with annoyed customers. Keep calm and things may be solved better and sooner.
