In its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies,“No, thanks. I've got a good horse under me.”

    The city planners decided to build an underground drainage(排水) system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.

    An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.

    This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire bulidings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like the Tremont Hotel, which was a six-story brick building?

    That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like Tremont Hotel, Pullman would place thousands of jackscrews(螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10 jackscrews. At Pullman's signal each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stayed open during the entire operation, and many of its guests didn't even notice anything was happening.

    Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.

    I was now in my twenty-third year of residence in this island and was so naturalized to the place and to the manner of living that I finally enjoyed the certainty that no savagesc(野人) would come to the place to disturb me, and that I could have been content to spend the rest of my time there, even to the last moment, till I had laid me down and died, like the old goat in the cave.

    I had also arrived to some little recreations and amusements, which made the time pass more pleasantly with me a great deal than it did before.

    At first, I had taught my Poll to speak. And he did it so familiarly and talked so clearly and plainly that it was very pleasant to me. And he lived with me no less than six years. How long he might live afterwards, I don't know; though I know people have an idea in Brazil that they live a hundred years. Perhaps poor Poll may be alive there still, calling Poor Robin Crusoe to this day. I wish no other English man the ill luck to come there and hear him. But if he did, he would certainly believe it was the devil.

    My dog was a very pleasant and loving companion to me, for no less than sixteen years of my time, and then died of mere old age.

    As for my cats, they multiplied to that degree that I had to shoot several of them at first to keep them from eating up all I had.

    Besides these, I had two more parrots which talked pretty well and would all call Robin Crusoe, but neither like my first. Nor indeed did I take the pains with any of them that I had done with him. I had also several tame sea-fowls, whose names I don't know, who I caught upon the shore and cut their wings and the little stakes which I had planted before my castle wall being now grown up to a good thick bush; these fowls all lived among these low trees and bred there, which was very agreeable to me; so that as I said above, I began to be very well contented with the life I led, if it might have been secured from the threat of the savages.

    One day in the gym, I asked a coach, "What's the difference between the best athletes and everyone else?" He briefly mentioned the things that you might expect: genetics, luck, talent.

    But then he added something I wasn't expecting. "At some point," he said, "it comes down to who can handle the boredom of training every day and doing the same practice over and over again."

    Most of the time people talk about getting motivated to work on their goals. As a result, I think many people get depressed when they lose focus or motivation because they think that successful people never lack motivation that they seem to be missing. But that's exactly the opposite of what this coach was saying.

    When I was an athlete, I loved going to practice the week after a big win. Who wouldn't? Your coach is happy, your teammates are excited, and you feel like you can beat anyone. As an entrepreneur, I love working when customers are rolling in and things are going well. Getting results has a way of pushing you forward.

    But what about when you're bored? What about when the work isn't easy? What about when it feels like nobody is paying attention or you're not getting the results you want? It's the ability to work when work isn't easy that makes the difference.

    If you look at the people who are consistently achieving their goals, you start to realize that it's not the events or the results that make them different. It's their commitment to the process. They fall in love with the daily practice.

    So, fall in love with boredom. Fall in love with repetition and practice. Fall in love with the process of what you do and let the results take care of themselves.

When I grow up

    In kindergarten, my class was asked to draw pictures, showing what we wanted to be when we grew up. Our drawings were expected to display our dream occupations. I remember pictures of ballerinas dancing, firefighters putting out a blaze, and astronauts leaping across the moon.

    My picture showed a figure with brown hair holding a box of orange juice beside a counter. Underneath was my handwriting: "When I grow up, I want to work at Market Basket because it would be fun to swipe (刷) orange juice across the scanner." Out of everything, my five­year­old self wished to work at the local grocery store.

    When we are young, questions of what we want to be when we grow up are common. Yet we are not expected to respond with an answer that is likely to come true. However, when we become teens, we are asked the very same questions twice as often. The difference is, now we are supposed to answer with confidence.

    Teens are expected to know exactly what we want to be and how we are going to achieve that goal. However, not all of us can be so sure. Even though I am in high school, I cannot answer with certainty. But I don't consider that a bad thing. How am I supposed to know what I will want to spend my time doing at age 40?

    When I think about the future, I definitely don't see myself working at Market Basket, but in reality, if that was what would make me happy, I would do it. So, the next time someone asks me what I want to be when I grow up, I will simply say "happy".

    Happiness is a destination for everyone. We may want to walk different paths in life, but we all want to be happy wherever we end up. Choose your path, but don't worry too much about choosing wisely. Make a mistake or two and try new things. But always remember, if you're not happy, you're not at the end of your journey yet.

    A new study has found the amount of antibiotics(抗生素)given to farm animals is expected to increase by two-thirds over the next 15 years. Researchers are linking the growing dependence on the drugs to the increasing need for meat, milk and eggs. However, the drugs could quicken the development of antibiotic-resistant infections(感染). Such infections are already a major public, health concern in the United States.

    The World Health Organization notes when people stop living in poverty(贫困), the first thing they want to do is eat better, rather than earn more money. For most people, that means their diet should contain more meat. With the rapid development of Asia, people there are eating nearly four times as much meat, milk and other milk products as they did 50 year ago.

    To meet the need, farmers have put many animals into smaller spaces. As the animals are crowded together, the easiest way to deal with some of the problems of crowding is to give them antibiotics. It's clear that antibiotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually.

    Nowadays, doctors find antibiotics that once worked against the infections no longer work. The bacteria have learned ways to fight against the drugs. The heavy use of antibiotics in animals is responsible for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year and at least 23,000 die from an infection.

    Europe has banned the use of antibiotics to increase animal growth. And the United States is hoping to persuade farmers to stop using antibiotics for that purpose.

Would you drink water that had once been flushed down a toilet? After it's been cleaned, that is. The climate is warming, and the population of drought-prone states California continues to grow. So recycling wastewater into drinking water may become a necessity.

But, it can be really hard for people to get over their disgust at the thought of drinking recycled water. People are grossed out by cycled water, because it was once wastewater—you know, the stuff that goes down your kitchen drains, your showers, your toilets. And even though it's cleaned up to a standard that is identical, if not better, than commercially bottled water, the key barrier to recycled water acceptance is people's disgust regarding it, " said Daniel Harmon, a psychologist in University of California.

In one experiment, the researchers had some participants watch a short video promoting water conservation. And in another experiment, they added a video explaining why recycled water might trigger disgust even though all pollutants have been removed. And neither video had a strong effect on people's willingness to drink recycled water or to support the practice.

The messages were not enough to get them to actually use recycled water more. "Disgust is such a powerful reaction that simply giving more information is not going to really be effective. " The study appears in the journal Basic and Applied Social Psychology.

Researchers say it's probably going to take a lot more to get people to embrace recycled water. For example, it might help to see members of their community drinking water that's gone, as it's called, from "toilet to tap, " with no ill effects.

It is clear that these kinds of more direct campaigns for acceptance are necessary to get people to get over that psychological barrier—to take that first sip, so to speak. Cheers!
