When my students ask me why I live in a tiny house, they ask it in light of all the “sacrifices(牺牲)”I an making. They know that I have moved from a large apartment in the city to a small custom-built home on wheels in the backyard woods. They know I forego running water, Internet connection, sewage(下水道), and reliable phone reception.

    However, it was possible for me to be truly happy while living with very few material things. My body responded well, in health, fitness and mood, to a schedule more consistent(一致的)with the natural day and night cycle. Observing the daily sunset, hosting friends for days at a time, reading, writing letters to my families and friends and exploring natural wonders in my spare time all were free and invaluable experiences.

    What was necessary to my survival proved to be a rather short list-healthy food, clean and drinkable water, heat source, weather-protecting shelter, weather-suitable clothing, equally important friends and mental and physical stimulations(刺激).

    When I returned to life in the US, I couldn't help but sense a deep and uneasy belief that life suddenly changed. I felt disconnected with many things- the earth, others, my food source, my waste disposal, the natural cycle of my body and the productive interests. These are the things I once cared for but now find myself too busy to enjoy. How was it that I was earning literally 40 times my Peace Corps salary and was less healthy, satisfied and intentional in my daily schedule? I found myself asking-what is it to be rich anyway? Therefore, last August I let go of most of my possessions and moved into a tiny house on wheels because I wanted to see if I could live a more enjoyable lifestyle. So far so good. No inconvenience has made up for the many positive benefits that continue to come from this change in lifestyle. I believe that I have made the right decision.

    Whenever the word “hero” comes to me, I immediately think of three Hs: honorable, hardworking, and happy. When I think more about this word, I picture someone who has accomplished good things for people and tries to do the right thing Hattie Elizabeth Alexander is one person whom I find to be very heroic.

    Hattie was born in Baltimore, Maryland on April 5, 1901. During her time at College she earned her Bachelor's Degree in Bacteriology and Physiology. These were just the first steps towards what she was finally going to be remembered for. After college Hattie attended Johns Hopkins School of Medicine and received her medical degree.

    After her education, she pursued her career, and after much time and hard work, she drastically reduced the number of infants(幼儿) dying from meningitis(脑膜炎). Hattie was very dedicated to her work and helped at as many locations as she could. Spending substantial(大量的) time in the laboratory, Hattie successfully developed a cure against the disease, which decreased the death rate to 20 percent. At the same time, she was also a teacher working with Columbia University.

    She was a caring lady interested in other people's lives. When she was teaching at Columbia University, other members would talk to her about students that were failing their classes, and somehow Hattie could always find convincing reasons as to why they should not be driven away. Later, Hattie became an instructor in Pediatrics at New York City's Babies Hospital. After many honors, she became the first woman president of the American Pediatric Society in 1965. This was her last major achievement, for soon after, Hattie died of cancer on June 24, 1968.

    Hattie is my hero because her positive attitude and strength helped her accomplish great things for others. She gave them her strength by developing medicines against diseased, which, by doing so, made them stronger. This is what makes Hattie Elizabeth Alexander my hero.

    Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.

    Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（猎食动物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.

    Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.

    Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.

    Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.

    Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them,  and they don't need to share their food.

    As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.

    You've heard of the fat suit and the pregnancy suit; now meet AGNES—the old person suit.

    AGNES stands for “Age Gain Now Empathy(换位体验)System” and was designed by researchers at MIT's AgeLab to let you know what it feels like—physically—to be 75 years old. “The business of old age demands new tools,” said Joseph Coughlin, director of the AgeLab. “While focus groups and observations and surveys can help you understand what the older consumer needs and wants, young marketers never get that Ah ha! moment of having difficulty opening a jar, or getting in and out of a car. That's what AGNES provides. ”

    Coughlin and his team carefully adjusted the suit to make the wearer just as uncomfortable as an old person who has spent a lifetime eating poorly and not doing much exercise. Special shoes provide a feeling of imbalance, while braces on the knees and elbows limit joint mobility. Gloves give the feeling of decreased strength and mobility in the hands and wrists, and earplugs make it difficult to hear high—pitched sounds and soft tones. A helmet with straps(带)attached to it presses the spine(脊柱), and more straps attached to the shoes decrease hamstring flexibility, and shortens the wearer's step.

    AGNES has been used most recently by a group of students working on a design of an updated walker. By wearing the suit they could see for themselves what design and materials would make the most sense for a physically limited older person. Coughlin said the suit has also been used by clothing companies, car companies and retail goods companies to help them understand the limitations of an older consumer.

    “AGNES is not the destiny of everybody,” he said. “She is a badly behaved lady who didn't eat and exercise very well. A secondary benefit we've found with AGNES is that it has become a powerful tool to get younger people to invest in their long-term health. ”

    I was deeply moved by the kindness of an elderly flower seller at Sydney's Central Station one evening.

    I was feeling as cold as the winter winds quickening the steps of the people who buried chins (下巴) in scarves and hands deep into coat pockets. In many ways, 2018 had proven an arduous year. My teenage daughter had left home for university, my job of 23 years was no more, and a creative project I'd given my all to for years had also been suddenly called off. I also found out a person I considered a friend was far from it.

    A year earlier, I'd dreamt about an earthquake. In the dream, a red light flashed inside a building and then the earth began to rock. Walls fell down on me as I ran into the open, feeling sorry for the people I hadn't loved enough. Before I was buried completely by the falling world, I shouted, "Abuelo, ayudame," in my native Spanish. "Grandfather, help me!"

    Now, with the very real aftershocks of a series of unexpected endings, I walked into a little flower shop to buy a gift for a friend. The gentleman at the shop looked at me and turned away for a moment, returning with a fragrant flower. "For you. You need to smile today," he said in a rich and beautiful accent, offering me the flower with eyes full of care. It took all my strength not to cry. Then he gave me a grandfatherly hug that made me want to tell him everything.

    Instead, I thanked him and headed for the train. How did he know? I wondered. For the first time in weeks, I felt hope.

    From composer, musician, and philanthropist (慈善家) Peter Buffett comes a warm, wise, and inspirational book that asks, "Which will you choose: the path of least resistance or the path of potentially greatest satisfaction?"

    You may think that with a last name like this, Buffett has enjoyed a life of endless privilege. But the son of billionaire investor Warrant Buffet says that the only real inheritance handed down from his parents is a philosophy: Build your own path in life. It is a principle that has allowed him to follow his own passions, establish his own identity, and achieve his own successes.

    In Life Is What You Made It, Buffett expounds on the strong set of values given to him by his trusting and broadminded mother, his hardworking and talented father, and the many life teachers he has met along the way.

    Today's society, Buffett assumes, has begun to replace a work ethic (准则), which enjoys what you do, with a wealth ethic, which honors the reward instead of the process. We confuse privilege with material wealth, character with external (外在的) recognition. Yet, by focusing more on substance and less on reward, we can open doors of opportunity and work hard toward a greater sense of achievement. In clear and brief terms, Buffett tells us a great truth: Life is random, neither fair nor unfair.

    From there it becomes easy to recognize the equal dignity and value of every human life—our circumstances may vary but our essence does not. We see that our journey in life rarely follows a straight line but is often met with false starts, crises, and mistakes. How we push through and insist on those challenging moments is where we begin to create the life of our dreams—from discovering our vocations (使命感) to giving back to others.

    Personal and instructive, Life Is What You Make It is about challenging your circumstances, taking control of your fate, and living your life to the fullest.
