Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.

We experience this tiredness in two ways: as start-up fatigue(疲惫) and performance fatigue. In the former case, we keep putting off a task because it has either too boring or too difficult. And the longer we delay it, the more tired we feel.

     Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The solution is obvious though perhaps not easy to apply: always handle the most difficult job first.

Years ago, I was asked to write 102 essays on the great ideas of some famous authors. Applying my own rule, I determined to write them in alphabetical(按字母顺序), never letting myself leave out a tough idea. And I always started the day's work with the difficult task of essay-writing. Experience proved that the rule works.

Performance fatigue is more difficult to handle. Though willing to get started, we cannot seem to do the job right. Its difficulties appear so great that, however hard we work, we fail again and again. In such a situation, I work as hard as I can-then let the unconscious take over.

      When planning Encyclopaedia Britannica (《大英百科全书》), I had to create a table of contents based on the topics of its articles. Nothing like this had ever been done before, and day after day I kept coming up with solutions, but none of them worked. My fatigue became almost unbearable.

      One day, mentally exhausted, I wrote down all the reasons why this problem could not be solved. I tried to convince myself that the trouble was with the problem itself, not with me. Relived, I sat back in an easy chair and fell asleep.

An hour later, I woke up suddenly with the solution clearly in mind. In the weeks that followed, the solution which had come up in my unconscious mind provided correct at every step. Though I worked as hard as before, I felt no fatigue. Success was now as exciting as failure had been depressing.

      Human beings, I believe must try to succeed. Success, then, means never feeling tired.

Visiting Joshua Tree National Park, California

    Joshua Tree National Park is nearly 800,000 acres (英亩) large and surrounds parts of the Mojave and Colorado Deserts in South-central California. Although deserted at first sight, the park is full of wildlife and provides a variety of entertainment activities from hiking to climbing. Within a three-hour drive, Joshua Tree National Park takes at least a full day to visit.

Things to do

    Hiking opportunities within the park include several choices, from 12 self-guided nature routines to all-day back-country hikes.

    Joshua Tree NP has nine camping grounds, and back-country camping is also allowed.

    Rock climbing is a popular activity in the park, which has 10 mountains greater than 5, 000 feet in height.

When to visit

    Joshua Tree NP is open 365 days a year, although the best time to visit is October through April, when temperature is milder. The peak season is when the wild flowers bloom, and the summer months are the least crowded.

What to bring

    In addition to your camera and telescope, be sure to carry lots of water. Park and guiding maps can be picked up at any of the three visitor centers.

Fees

    Parking fees: You can buy a seven-day vehicle permit (周票) for $ 15, a single entry permit for $ 5, or Joshua Tree National Park annual (每年的) pass for $ 60.

    Camping fees: They vary by camping ground

    Sometimes the toughest thing about feelings is sharing them with others. Sharing your feelings helps you whether your feelings are wonderful or terrible. Sharing also helps you to get closer to people you care about and who care about you. But how?

    You can't tell your friends what's inside your backpack if you don't know what's in there yourself. Feelings are the same way. Before you can share them with anyone, you have to figure out what feelings you have.

    Making a list of your feelings can help. You can do this in your mind or by writing it out or even by drawing pictures. Is something bothering you? Does it make you frustrated or terrified? Do you feel this emotion only once in a while or much of the time?

    The way a person feels inside is important. If you keep feelings locked inside, it can even make you feel sick! But if you talk with someone who cares for you, you will almost always start to feel better. It doesn't mean your problems and worries magically disappear, but at least someone else knows what's bothering you and can help you find solutions.

    Your mom and dad want t0 know if you have problems and what's happening in your life. But what if a kid doesn't want to talk with parents? Then find another trusted adult, like a relative or a teacher at school. Maybe this person can help you talk with your parents about your problem or concern.

    Once you know who you can talk with, you'll want to pick a time and place to talk. You can talk publicly in your family. But some kids are more private than others and they will feel shy about sharing their feelings. Then find a quiet place or write it down on a piece of paper. A kid doesn't have to share every feeling he or she has.

    The human face is a remarkable piece of work. The astonishing variety of facial features helps people recognize each other and is vital to the formation of complex societies. So is the face's ability to send emotional signals, whether through an unconscious red face or the artifice of a false smile. People spend much of their waking lives reading faces, for signs of attraction, hatred, trust and fraud. They also spend plenty of time trying to hide true feelings or intentions.

    Technology is rapidly catching up with the human ability to read faces. In America facial recognition is used by churches to track worshippers' attendance; in Britain, by retailers to spot past shoplifters. In China, it confirms the identities of ride-hailing drivers, permits tourists to enter attractions and lets people pay for things with a smile. Apple's new iPhone is expected to use it to unlock the home screen.

    Set against human skills, such applications might seem incremental(增值的). Some breakthroughs, such as flight or the Internet, obviously transform human abilities; facial recognition seems merely to encode(编码)them. Although faces are unique to individuals, they are also public, so technology does not, at first sight, interfere with something that is private. And yet the ability to record, store and analyze images of faces cheaply, quickly and on a vast scale promises one day to bring about fundamental changes to opinions of privacy, fairness and trust.

    Start with privacy. One big difference between faces and other biometric data, such as fingerprints, is that they work at a distance. Anyone with a phone can take a picture for facial-recognition programs to use. Facebook's bank of facial images cannot be used by others, but the Silicon Valley giant could obtain pictures of visitors to a car showroom, say, and later use facial recognition to serve them ads for cars. Law-enforcement agencies now have a powerful weapon in their ability to track criminals, but at enormous potential cost to citizens' privacy.

    The face is not just a name-tag. It displays a lot of other information—and machines can read that, too. Again, that promises benefits. Some firms are analyzing faces to provide automated diagnoses of rare genetic conditions, far earlier than would otherwise be possible. Systems that measure emotion may give autistic(孤独症的)people a grasp of social signals they find difficult.

    The American dream is the faith held by many people in the United States of America that through hard work, courage, creativity and determination, they can achieve a better life for themselves. More specifically, they agree on how to get ahead in America: get a college education, find a reliable job, and buy their own house. But do Americans still believe in that path, and if they do, is it attainable?

    The most recent National Journal poll(民意测验，投票) asked participants about the American dream, what it takes to achieve their goal, and whether or not they felt the control over their ability to be successful. Obviously, the results show that today, the idea of the American dream and what it takes to achieve it looks quite different from it did in the late 20th century. By the large, people felt that their actions and hard work — not outside forces — were the deciding factors in how their lives turned out. But the participants had definitely mixed feelings about what actions make for a better life in the current economy.

    In the last seven years, Americans have grown more pessimistic about the power of education to lead to success. Even though they see going to college as a fairly achievable goal, a majority 52 percent think that young people do not need a 4-year college education in order to be successful.

    Miguel Maeda, 42, who has a master's degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability(稳定) his parents and grandparents never did. While some, like Maeda, emphasized the value of a degree rather than the education itself, others still see college as a way to gain new viewpoints and life experiences. Sixty-year-old Will Fendley, who had a successful career in the military and never earned a college degree, think “personal drive” is far more important than just go to college. To Fendley, a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook(支票簿), are the necessary elements for a successful life in America.
