Even when you're extremely busy, you aren't using your time with 100% efficiency. There are gaps in everyone's schedule where they aren't doing anything important. Even if your schedule hasno gaps, there is probably lots of time where you aren't working as fast or as effectively as you possibly could.

    Why aren't you completely efficient? It's because time isn't thelimiting factor. If it were the limiting factor, people could work non-stop without breaks or any unproductive distractions. Instead, people, even those who are highly productive, need to take breaks, occasionally procrastinate(拖延) and slow downon tasks throughout the day.

    The real and most important limiting factor for productivity is your energy levels to pay attention. Energy levels limit your productivity because when you're tired, you can have ample time and still not get everything done. Your attention ability is also limited, because even if there are amillion things that need to be done, you can only focus on one or two at a time.

    You might not be able to insert another 4-5 hours into your schedule without making some sacrifices. But even extremely busy people can addan hour or two into their schedule without can celling anything. The reason it's hard to “find time” isn't a lack of time. It's because you don't have enough energy left to focus on something else that needs to fit into your day.

    I first suspected time wasn't the real problem during an extremely busy period in my life over a year ago. I was insanely busy, but at that time I still exercised regularly. I had daily-to-do lists with over twenty items, and I still found time to exercise. However, after a few weeks off, due to illness, stopped exercising. I was not busy by any standards, in fact, my schedule was incredibly light. Despite this free time, I found it hard to find time to exercise. It seemed to get pushed later and later into my schedule until it was gone. How can I explain this odd experience? I believe you haveknown it.

    Singapore is building an airport where indoor trees, waterfalls and a 'rain vortex' sit alongside check-in queues, waiting rooms and baggage carousels(传送带).

    Where once sat a car park, there will soon be thousands of trees and plants across 22,000 square metres of landscaped indoor parklands. This will be joined by a 40m-high indoor waterfall, expected to be the world's tallest. These are the plans for the new 3.5 hectare 'Jewel' development at Singapore's Changi Airport, scheduled to open in 2018; a five-story, 134,000 square metre complex, mixing natural outdoor plants with modern airport facilities.

    “The aim behind the introduction of such lush(茂盛的) landscaping is purely to provide all visitors with a memorable experience, one where they are surrounded by nature and greenery,”says Philip Yim, Chief Executive Officer of Jewel Changi Airport Development.

    Promised sustainability（持续性） measures include “extensive usage of photovoltaic panels（光电板）”to produce renewable energy, as well as encouraging the use of natural lighting and a “high efficiency” air-conditioning system.

    The indoor waterfall, named the “Rain Vortex”, will make use of special lighting effects to change at night into what is promised to be a dramatic light and sound show. “The Rain Vortex is one example of how sustainable design plays an important role in the planning of the attraction,” says Yim. 'In the event of a rain storm, the power of the rain water will flow naturally through the oculus. The excess rain water collected will be used for irrigation of the landscaping at Jewel.'

    Yim quotes the popular reputation Singapore enjoys as “the garden city”, where greenery is recognised as an essential part of the urban landscape, an attractive image which clearly inspires Jewel's design.

    However, it remains to be seen whether, beyond the aesthetic (审美的) appeal, Jewel can add genuine environmental things to something as un-environmental as an international airport.

    Next morning, there was no wind and we were half a mile from the eastern coast of the island. Although the sun shone bright and hot, I hated the thought of Treasure Island, afraid of what would happen there.

    Guns were given to all the honest men. Hunter, Joyce, and Redruth were told what was happening, and were less surprised than we expected them to be. Then the captain went on deck to talk to the crew.

    They all became happier at once. I think they thought they would find the treasure lying around on the beach! After some talk, six men stayed on board, and the others, with Silver, got into the small boats.

    I then had the first of the mad ideas that help ed to save our lives. If six men were left, we could not take control of the ship; and because only six were left, the captain's men did not need my help. So I quickly went over the ship's side and into the nearest boat.

    No one took much notice of me, only one man saying, “Is that you, Jim?” But Silver called from the other boat, wanting to know if it was me. Then I began to worry if I had done the right thing.

    The crews rowed to the beach and our boat arrived first. I ran towards the trees. Silver and the rest were a hundred metres behind, and I heard him shouting, “Jim, Jim!” But I took no notice, pushing through trees and bushes, and ran until I could run no longer.

    I was pleased to lose Long John and began to enjoy looking around this strange island. I crossed wet ground and came to a long, open piece of sand, then went on to a place where the trees had branches that were thick and close to the sand.

    Just then I heard distant voices, Silver's among them, and hid behind a tree. Through the leaves, I saw Long John Silver and another of the crew talking together.

    “I'm warning you because I' m your friend, Tom,” Silver was saying.

    “Silver,” said Tom: “You're old and you're honest, or so men say; and you've money, too, which lots of poor seamen haven't. And you're brave. Why let yourself be led away with that kind of scoundrel? I'd rather die than—”

    Suddenly, there was a noise of distant shouting, then a long horrible scream. I had found one honest man here, and that terrible, distant scream told me of another．

    “John!” said Tom: “What was that?”

    “That?” replied Silver. His eyes shone like pieces of broken glass in the sun: “That'll be Alan.”

    “Alan!” cried poor Tom: “An honest and true seaman! John Silver, you've been a friend of mine, but for no longer. You've killed Alan, have you? Then kill me, too, if you can!”

    The brave man turned his back on Silver and began to walk back to the beach. With a shout, Silver threw his crutch through the air. It hit poor Tom between the   shoulders, and he fell to the ground with a cry.

    The Oklalhoma teen's eyes were covered by two blindfolds（眼罩）. She didn't know she would meet her father, James, after 12-year separation.

    “I had actually discussed with her the night before at a restaurant and talked over the details of where we would go and how we would pull them of,” said Amanda, Rory Beth's mother.

    A video shows Amanda led her blindfolded daughter out of their car and guided her across the parking lot of Broken Arrow Lanes in Broken Arrow.

    Little did she know, her father was on the sidewalk holding a birthday cake that read, “Happy Birthday Rory Beth, Love Dad.” When the teen slowly pulled down her blindfolds, she was extremely surprised. Both the father and daughter stood silently looking at each other until James finally walked over and hugged her. James only broke their embrace to look at his daughter and hold her face. “There were definitely lots of tears from James, myself, and boys, and even a few bystanders,” said Amanda.

    James was a truck driver who spent a lot of time on the road, so Amanda ended the marriage with him when Rory Beth was a baby. “It was hard to figure out how to make it work,” Amanda said. Amanda felt Rory Beth was now old enough to understand and to ask any questions she may have, so the reunion happened.

    The birthday surprise was on June 4, and the father and daughter had seen each other again since, even celebrating Father's Day together. Amanda said her daughter and James were both delighted to be together.

    “She's already calling him 'daddy' and tells him that she loves him.” Amanda said.

    Sports are the base of my life, next to my mother who raised me when my dad left us. I have been into sports since I was six years old. I have known many coaches and heard hundreds of their tips, but they usually focused on drills to develop my skills and reach the next level of play.

    When I was in Senior Two, I met the new school basketball coach, Brian Pawloski. I thought I was certain to be selected for the school team since I had been in it the year before. I showed up to the tryouts and put out about 90% effort since I thought I'd make it with no problem. That was a big mistake.

    Brian Pawloski is the hardest-working coach I have ever met. He didn't expect 100% effort, he expected 200% effort. One example: he once made us do 40 suicide drills for the 40 lay-ups (投篮) we missed in a game. Some think this is crazy, but it isn't. After this conditioning practice, as we were getting a cup of cold water to drink, I said, "coach, that was the best practice I ever had." I was completely sincere. This man was and is the person who influenced me most at my high school. He expects us to be excellent not just on the court but in the classroom. If I am not working on basketball, I am reading a book that he thinks will help us better understand life's challenges, including Wooden, Coach, and The Screwtape Letters.

    In the first two years I slacked off, not putting forth my full potential. Now, unlike the coaches of my youth, this man was interested in how he did off the court. He always made sure I kept up with my studies and was able to be trusted. I can honestly say that on other coach has given me so much advice on how to succeed in basketball, but more importantly, in life. My school is lucky to have such a great person to teach, coach and influence their students. I will always remember my high-school basketball days as one of the hardest times I have ever worked in my life not only in basketball but in my growth as an individual.

    For several decades, there has been an organized campaign intended to produce distrust in science, funded by those whose interests are threatened by the findings of modern science. In response, scientists have tended to stress the success of science. After all, scientists have been right about most things, from the structure of the universe to the relativity of time and space.

    Stressing successes isn't wrong, but for many people it's not persuasive. An alternative answer to the question "Why trust science?" is that scientists use the so-called scientific method. But what is called the scientific method isn't what scientists actually do. Science is dynamic: new methods get invented; old ones get abandoned; and at any particular point, scientists can be found doing many different things. False theories sometimes lead to true results, so even if an experiment works, it doesn't prove that the theory it was designed to test is true.

    If there is no specific scientific method, then what is the basis for trust in science? The answer is the methods by which those claims are evaluated. A scientific claim is never accepted as true until it has gone through a long process of examination by fellow scientists. Scientists draft the initial version of a paper and then send it to colleagues for suggestions. Until this point, scientific feedback is typically fairly friendly. But the next step is different: the revised paper is submitted to a scientific journal, where things get a whole lot tougher. Editors deliberately send scientific papers to people who are not friends or colleagues of the authors, and the job of the reviewer is to find errors or other faults. We call this process "peer review" because the reviewers are scientific peers—experts in the same field—but they act in the role of a superior who has both the right and the responsibility to find fault. It is only after the reviewers and the editor are satisfied that any problems have been fixed that the paper will be printed in the journal and enters the body of "science."

    Some people argue that we should not trust science because scientists are "always changing their minds." While examples of truly settled science being overturned are far fewer than is sometimes claimed, they do exist. But the beauty of this scientific process is that science produces both creativity and stability. New observations, ideas, explanations and attempts to combine competing claims introduce creativity; transformative questioning leads to collective decisions and the stability of scientific knowledge. Scientists do change their minds in the face of new evidence, but this is a strength of science, not a weakness.
