It's a Friday morning in Boston, which1Dr. Jim O'Connell is making his rounds. He might be more2inside an exam room, but that's not where his patients are. Dr. Jim O'Connell is one of a handful of physicians making house calls to the3in the city.

    More than 550, 000 Americans are homeless, and many have health problems but no4to cure. O'Connell and his team are doing something about it. On a daily routine, they5about 700 regular patients. "I feel like I'm a country doctor in the middle of the city." he said.

    O'Connell began to do this 33 years6, when he was at Harvard Medical School and was7to be a one-year position as the founding physician of a new health-care program for Boston's homeless. That turned into a 33-year8at the Boston Health Care for the Homeless Program, one of the country's largest of its kind. O'Connell9about everything, from stitches (缝补)for an arm to surgery for the soul. If patients can't be treated on the street, he finds them a treatment bed at the respite facility(休息治疗区), a place for patients10are too sick to be on the streets11not ill enough for a hospital stay.

    "12I had been taught to do—go fast, be efficient—was13when you take care of homeless people." When you see somebody outside, you get them a cup of coffee and sit with them. Sometimes it14six months or a year of offering a sandwich or a cup of coffee before someone would start to talk to me. But15they engage(参与), they'll come to you any time because of16you. When asked about how his life might have17, if he had become a highly paid physician, O'Connell said, "I18think about it anymore."

    Some things are far more valuable than money. Just ask Dr. Jim O'Connell who19 everything from patients who have nothing20to give.

    Be a Traveler, not a Tourist

    Last summer, I had just enough money saved to buy a golden ticket—a 3-month train pass that would take me to the furthest reaches of Europe. Excited for my journey, I packed all the necessities(生活的必需品)—except the 1.

    While the convenience of the Internet was definitely a contributing factor to my 2not to take with me the few expensive kilograms of out-of-date information, this was not the only reason why I decided to fly alone.

    To be honest, my main 3with the guidebook is that I find it4 the pleasure of a journey—like bossy aunt who is always telling you what to do, 5 she doesn't always know what is the best.

    Experience has taught me that there is an obvious 6 between a tourist and traveler.

While waiting in a queue, I met a man who had a checklist. He showed me his list of “Top 20 Things To Do in Italy” and 7 off in a loud American accent that he'd seen everything Italy has to offer in just four days.

    The problem I had with this man's 8 to travelling was that he was too 9 information provided by his guidebook. He was lost in the 10 attractiveness of the “must-sees” and 11 to all the wonders and adventures that might happen during the 12 trip.

    So, 13any guidebook, I traveled to Estonia, the tiny Baltic country bordering Russia. In the 14 of advance plans as guidebooks would suggest, I had no choice but to turn to some friendly faces for advice. I 15myself first and then asked them what was happening around the town. When this 16 an invitation to a beautiful Estonian home by a river where I 17 a 110-degree wood-stove sauna（桑拿浴）, 18 picked forest-mushrooms and the good 19 of our five newfound Estonian friends, I was most glad that I had left my “bossy 20” at home.

    I was walking around in a Big Bazar store doing a shopping, when I saw a Cashier talking to a boy who couldn't have been more than 5 or 6 years old. The Cashier said, "I'm sorry, 1you don't have enough money to buy this doll." Then the little boy turned to me and asked, "Uncle, are you sure I don't have enough money?"

    I 2 his cash and replied, "You know that you don't have enough money to buy the doll, my dear." The little boy was still holding the doll in his hand. Finally, I walked 3 him and I asked him 4 he wished to give this doll to. "It's the doll 5 my sister loved most and wanted so much. I wanted to gift her for her Birthday. I have to give the doll to my mommy so that she can give it to my sister when she goes there." His eyes were so 6 while saying this.

    "My Sister has gone to be with God. Daddy says that Mommy is going to see God very soon too, so I thought that she could take the doll with her to give it to my sister." My heart 7 stopped. The little boy 8 me and said, "I told daddy to tell mommy not to go 9. I need her to wait until I come back from the mall."

    Then he looked again at the 10with sad eyes, very quietly. I quickly11 for my wallet and said to the boy. "Suppose we check again, just 12 you do have enough money for the doll?" I added some of my money to his, without him seeing and we started to count it. There was enough for the doll and even some13money.

    The little boy said, "Thank you God for giving me enough money! I asked last night God to 14 I had enough money to buy this doll. He heard me! I also wanted to have enough money to buy a white rose for my mommy, but I didn't 15 to ask God for too much. But He gave me enough to buy the doll and a white rose. "

    I finished my shopping in a totally different 16from when I started. I couldn't get the little boy out of my mind. Then I remembered a local newspaper article two days ago, which mentioned a 17 man in a truck, who hit a car occupied by a young woman and a little girl. The little girl died right away, and the mother was left in a 18 state.

    The love that the little boy had for his mother and his sister is 19, to this day, hard to imagine. And in a 20 of a second, a drunk driver had taken all this away from him.

    At the beginning of our next class, I asked if someone wanted to share what happened when they told someone they loved them. As was usually the 1, I fully expected one of the women to2 , but on this evening one of the men raised his hand. He appeared quite moved and a bit3 .

    He began by saying, “Dennis, I was quite4 with you last week when you gave us this 5 I didn't feel that I had anyone to say those words to, and6, who were you to tell me to do something that is 7? But as I began driving home a8 deep down in my heart started talking to me. It was 9me that I knew exactly who I needed to say 'I love you' to. You see, five years ago, my father and I had a cruel 10and really never resolved it since that time. We 11seeing each other unless we totally had to at Christmas or other family 12. But even then, we13 spoke to each other. So, last Tuesday by the time I got home I had14 myself I was going to tell my father I loved him.”

    “It's15, but just making that decision16to lift a heavy load off my chest.”

    “When I got home, I rushed into the house to tell my wife what I was going to do. She was already in17 , but I woke her up anyway. She catapulted (弹射) out and 18 me, and for the first time in our married life she saw me cry. We19half the night drinking coffee and talking. It was20.”

    Before volunteering to teach in Tanzania, I not only learned local language and custom, but also learned the school I would teach in. So I thought I had good 1 before I stepped into my classroom. I was eager to teach them. First, I2myself to let the students know me. Then, I started to learn the students' names.

    Back in America, I would 3 learn the students' names because I had a special method. However, there as the students said their names, I soon realized that method became 4 . I only learned Glory's name on the first day 5 her constant smile and dimples(酒窝).

    In the following days, only one student asked questions in class while most were not 6 at all. In order to 7 a connection with them, I asked them to regularly write me a letter about their families or interest. When they were writing to me, I was like a 8to them. They regularly poured their thoughts and secrets to me. I learned Glory was sad about her mother's 9. She wished to see her again in heaven. As students 10 to me, I included their interest into my lessons. However, I11 to let most students participate in class activities regardless of my efforts. I was filled with12 .

    Then, one day, everything 13. In the class of that day, without much thinking, I asked Glory if her parents had dimples. Glory's eyes suddenly became 14. She said softly with tears in her eyes, "My mother had." Then all students' backs bent much lower and the class became more 15. My mind flashed to her letters about her mother. I continued speaking, not as an English teacher, but as someone who truly16 my student, "Glory, you have your mother's dimples. So whenever you smile, your mom is with you."

    She looked at me, smiled, then reached up and felt her dimples."17?" she asked. "Yes," I replied. She continued to  18 her cheeks. I added, "19your mom is gone, she will always be in those dimples." Hearing those words, many students felt 20. They began to love me and raise hands in class.

As a primary school student in New York City, Robert Lee would stare in 1 at his classmates throwing away half-eaten sandwiches after lunch, because his parents had 2 him and his elder brother not to 3 food. They said it was bad karma(作孽).

    While studying at New York University, Robert remembered this4 and joined Two Birds One Stone, a food-rescue club on campus that5, five days a week, uneaten pasta, vegetables, and other leftovers from the school 6to nearby homeless shelters.

When Robert and fellow club member Louisa Chen entered a college contest, they 7 a slightly 8 idea for a food-rescue nonprofit group: Their program wouldn't have a 9minimum, would 10seven days a week, and its staff would 11volunteers.

Their idea12the competition. With the＄1,000 prize, they13Rescuing Leftover Cuisine (RLC) in July, 2013. In just the first few weeks, Robert's team delivered a donation of enough spaghetti and meatballs to14 20 people in line at a New Yorker City homeless shelter that had 15food.

Robert, who had taken a job as an analyst at J.P.Morgan, devoted his spare time to creating a network of New Yorker City restaurants that were16to donate food, and he enlisted(征募) volunteers to make food deliveries to homeless shelters. After RLC received national press17, homeless shelters and soup kitchens in many places reached out to Robert for18. Two years after being founded, RLC had already distributed more than 250,000 pounds of food.

    Only a year into his finance job, Robert gave up his six-figure salary to19RLC. "I compared work at J.P.Morgan with that at RLC, and the difference was great," he says.

    "One shelter told us that our donations allow them to provide entire dinners for more than 300 people, three nights a week," Robert says. "Things like that make me feel20that I quit my job."
