Blind imitation is self-destruction. To those who do not recognize their own unique worth, imitation appears attractive; to those who know their strength, imitation is unacceptable.

    In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes and turned out some tasty dishes. But soon I grew bored. Why follow someone else's way of cooking when I could create my own? Imitating role models is like using training wheels on a child's bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.

    In daily life, imitation can hurt us if we subconsciously (下意识地）hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others.

    In the field of entertainment, our culture praises and admires celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors.

    Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.

Study your role models, accept the gifts they have given, and leave behind what does not serve you. Then you can say, "I stand on the shoulders of my ancestors' tragedies and declare victory, and know that they are cheering me on."

    Can technology improve your trip? Meet Judy Williams. When she and her husband recently checked into Blu Hotel in Zurich, a clerk asked them to sign the dotted line on a room rate hundreds of dollars higher than their online offer.

    “It was not a cheap stay,” says Williams, a lawyer from Billings, Mont. But it became more of one after her husband fired up the Booking.com app he'd used to book their room on his smart phone. “As soon as we showed him the cost, he honored it,” Williams says.

    Technology may create challenges for travelers but it can also solve them. It's more than making sure of a hotel cost. The latest Booking.com can help users select hotels by location, make a secure booking and view the confirmed (已确认的) cost so they never need to re-discuss their hotel price.

    Another pain point for travelers is traffic that eats away precious vacation time. There's a new app called Commute which is aimed at users who have to make the same trip every day. But if you're headed to Los Angeles or Honolulu, where visitors can easily get stuck in hours of heavy traffic, Commute can help.         

    Just input basic information about your destination and expected leaving time, and the app will start sending you traffic information 15 minutes before you leave. Testing Commute proved to be a challenge for me, because my home address is about 900 miles from my place of work. But if you have only a short distance to travel through a heavily populated area, you can use Commute to avoid traffic jams.

    Another source of travel-related problems is money. That's particularly true when you're dealing with a foreign currency. The latest Travel Money Tracker helps travelers prevent currency mix-ups. It immediately changes a country's native currency to yours, so you know exactly how much that Espresso (浓咖啡) in Milan costs in dollars. It can also warn you when you're overspending, which can sometimes be a problem when you're on vacation. The only catch, of course, is that you have to remember to record all your purchases.

    Taken together, these apps solve some of the most common travel problems. But not all of them. Some things, no smart phone can fix, which means I get to keep my job – for now at least.

    Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood．When I was a boy of 12 in South Carolina, something happened to me that cured me forever of wanting to put any wild creature in a cage.

    We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the trees and sing. There isn't a musical instrument made by man that can produce a more beautiful sound than the song of the mockingbird.

    I decided that I would catch a young bird and keep it in a cage and in that way would have my own private musician.

    I finally succeeded in catching one and put it in a cage. At first, in its fright at being captured, the bird fluttered about the cage, but eventually it settled down in its new home. I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.

    I had left the cage out on our back porch, and on the second day of the bird's captivity my new pet's mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.

    The following morning when I went to see how my captive（被俘虏的） was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened! I had taken excellent care of my little bird, or so I thought.

    Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had occurred. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries. She thinks it better for her young to die than to live in captivity.”

    Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.

    Elephants are able to know the difference between a man and a woman, and can tell an adult (成年人) from a child—all from the sound of a human voice. This is according to a study in which researchers played voice recordings to wild African elephants.

    The animals showed more fear when they heard the voices of adult Masai men. Usually Masai people hunt elephants, and this suggests that animals have grown to listen for and avoid them.

    Prof. Karen McComb and Dr Graeme Shannon from the University of Sussex led the study. They explained that in former research they had used similar experiments to show that elephants could tell—from the sound of a lion—whether the animal was a female (雌性) or a more dangerous male (雄性).

    Prof. McComb wanted to find out if the animals used their very sharp sense of hearing to recognize danger from humans.

    The scientists recorded Masai men, women and children saying, in their own language, “Look, look over there, a group of elephants are coming.” They also recorded Kamba men saying this phrase.

    Masai people often come across elephants, which can result in violent (暴力的) hunting. Kamba people, however, mainly feed on agriculture, which does not generally bring them into violent touch with the animals.

    When the team played recordings of these different voices through a hidden speaker, they found that elephant family groups showed more fear in response to the voice of a Masai man, than to a Kamba man's voice. And the adult male Masai voices caused far more violent response than the voices of women or boys.

    When I was 8 years old, I decided to run away from home after a quarrel with my mother. With my suitcase(行李箱) packed and some sandwiches in a bag, I started for the front door.

    My mom asked where I was going. “I'm leaving home,” I said.

    “What's that you're carrying?” she asked.

    “Some clothes and food,” I replied.

    “If you want to run away, that's all right,” she said. “But you came into this home without anything and you can leave the same way.”

    I threw my suitcase and sandwiches on the floor and started for the door again.

    “Wait a minute,” Mom said. “You didn't have any clothes on when you arrived, and I want them back.”

    This infuriated me. I tore my clothes off — shoes, socks, underwear and all — and shouted, “Can I go now?”

    “Yes,” my mom answered, “but once you close that door, don't expect to come back.”

    I was so angry that I shut the door forcefully and stepped out of my home. Then I noticed down the street two neighbor girls walking toward our house. I was so shy that I saw the big spruce (云杉) tree in our yard and jumped under the low-hanging branches (树枝). A pile of dried-up brown needles (针状物) were beneath the tree, and you can't imagine the pain those sharp needles caused to my body.

    After I was sure the girls had passed by, I ran to the front door and knocked at it loudly.

    “It's Billy! Let me in!”

    The voice behind the door answered, “Billy doesn't live here anymore. He ran away from home.”

    Looking behind me to see if anyone else was coming down the street, I said, “Mom! I'm sorry. I'm still your son. Let me in!”

    The door opened and Mom's smiling face appeared. “Did you change your mind about running away?” she asked.

    “What's for supper?” I smiled back.

    On the first day of my new high school, I almost had a nervous breakdown. Everything about the school seemed so difficult. When I got home, my parents said, "You're nervous and that's okay. Everyone is afraid of high school." I denied it. I wanted to be strong, so I refused to let anyone know about my fear, even my closest friends.

    On the first day I was late for every class and was constantly lost. The school seemed like a puzzle that I couldn't figure out. Was this how the whole year was going to be? I didn't think I could rise to this challenge, especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with it!

    Despite my fears, after the first week I finally had my schedule figured out. With the exception of falling up and down the stairs a couple of times and getting laughed at, high school was turning out to be not so bad. It was actually much better than middle school and much more challenging. Since then, I've been elected（选举）vice monitor of my class, which wasn't much of a victory since only three people ran for the four positions.

    It is normal to be scared about a new school. Take a deep breath and relax. High school is something that any student can overcome. Make sure you participate in some out-of-class activities because you'll find it easier to make friends. Try to do your best  even if it isn't straight A's.

    Most important of all, be who you are, whether you're a "fool"， an athlete, or a lower grader. Don't try to pretend to be someone you're not. Now you know the true secrets of high school.
