Stop wasting your time thinking of reasons for your failures and shortcomings.  Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.

    The seeds, and the power to grow them, are contained in the most awesome machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.

    You cannot be successful without first developing your self-esteem (自信心). Your level of self-esteem is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self-esteem are people who do not believe that they have any power，or responsibility for their lives. They are always victims. They are leaves tossed (摇摆) by the winds of chance blown about with any sudden change in the weather.

    You can exercise control over your life only to the degree that you believe you are responsible for everything that happens in your life.  Failures think that everything happens by accident and chance. Successful people realize that they are responsible.

    Everything happens as a result of something.  If we can identify the cause，we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.

    If you associate with positive-thinking people，you are definitely going to achieve success. On the contrary，the opposite happens. We are responsible for finding，planting，and nurturing (培育) the seeds that contain future victory, born from setbacks (挫折).

    In short, in all areas of your life，whether they are financial, physical, emotional, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it. You are on the road to success.

Ways to sleep smarter

    Studies show that poor sleep influences people to make good decisions, concentrate on tasks or even manage a friendly mood(情绪) at work. {#blank#}1{#/blank#} Today we've got our top favorite sleep tips and facts.

Set a regular bedtime

    {#blank#}2{#/blank#}Choose a time when you normally feel tired. Try not to break this routine(惯例) on weekends when you will probably stay up late. If you want to change your bedtime, make the change gradually, such as 15 minutes earlier or later each day.

Eat the right food

    Some foods are more helpful to a better night's sleep than others.{#blank#}3{#/blank#} Others like bananas, potatoes, and whole-wheat bread are also helpful.

    Exercising provides lots of good health benefits(好处). A good night's sleep is one of them. But make sure you exercise in the morning or afternoon. The National Sleep Foundation reports that exercise in the morning or afternoon can help deepen sleep. However, those who worked out in the evening hours saw little or no improvement in their sleep.

Reduce(减少) screen time before bed

    {#blank#}5{#/blank#} A recent study shows that people who use electronic media(媒体) just before bedtime report lower-quality sleep even when they get as much sleep as those who don't.

A. Avoid the alarm clock.

B. Exercise to improve sleep.

C. Try to solve problems in your sleep.

D. Go to bed at the same time every night.

E. There are many ways to increase the quality of your sleep.

F. Everybody knows that warm milk helps people sleep better.

G. Stop watching TV just before bedtime and you'll sleep better.

    Joy Mangano was 33 and divorced. She had three kids under age 7, and was barely keeping up payments on her small two-bedroom home by working extra hours as a waitress. “There were times when I would lie in bed and think, I don't know how I'm going to pay that bill,” Mangano says.

    But he had a special ability for seeing the obvious thing. She knew how hard it was to mop the floor. “I was tired of bending down, putting my hands in dirty water, wringing (拧) out a mop,” Mangano says. “So, There's gotta be a better way.

    How about a “self-wringing” mop? She designed a special tool you could twist in two directions at once, and still keep your hands clean and dry. She set out to sell it, first a few at flea markers.

    Then Mangano met with the media. But would couch potatoes (电视迷）buy a mop? The experts on shopping TV were less than certain. They gave it a try, and it failed. Mangano was sure it would sell if they'd let her do the on-camera display. She said, “Get me on that stage, and I will sell this mop because it's a great item.”

    So QVC, a multinational corporation specializing in televised home shopping, took a chance on her. “ I got onstage and the phones went crazy. We sold every mop in minutes.”

    Today she's president of Ingenious Designs, a multimillion-dollar company, and one of the stars of HSN, the Home Shopping Network. Talking about the household invention, Mangano says, “It is as natural for me as it is for a parent to talk about their child.”

    When you eat fish, you probably eat it off a plate, using a fork. Well, the dolphins in Shark Bay, Australia, eat their fish from conch（海螺）shells!

    Scientists have found some of these bottlenose dolphins（宽吻海豚）using their large beaks to trap fish in shells underwater. Then, carrying the shells to the surface, they shake out the fish into their mouths and eat them. Clearly, using the conch shells allows the dolphins to catch more fish than they would be able to without such a tool. The technique has been called "conching".

    Researchers noticed dolphins engaging in the behavior a handful of times from 2007 to 2009. This dolphin trend seemed to become popular.

    Simon Allen, a scientist, was surprised to see the conching technique spreading. "In the lasts four months alone, the research team have seen and photographed the behavior no less than six times, possibly even seven," he said in a press release. He thinks the dolphins may be learning conching from one another.

    Dolphins are known to be highly intelligent. The size of their brain is large in proportion（比例）to their body size. Compared with other animals, they have highly developed communication and social skills. This species of dolphin also uses other tools. They will break off pieces of sponges that grow in the ocean, for example, and use them to cover their beaks. This allows them to search for food on the ocean floor without hurting their noses.

    Scientists are going to keep trying to catch the dolphins in the act of conching. They hope to see evidence of the dolphins teaching one another the technique. They also want to know how the dolphins get fish in the conch shell. Do they push the fish into the shell with their beaks? Or do they chase the fish into the shell before carrying them up to eat?

    However they do it, Allen believes these dolphins to be particularly clever. "I wouldn't be too surprised to find such cunning ploys being adopted by Shark Bay's bottlenose dolphins," he said in statement.

    After photographer Monni Must's daughter Miya died, the sad mother adopted her black dog, Billy Bean. As Billy became increasingly weak, the thought of its dying was just more than Must could handle. So she decided to clone the dog. “I feared everyone was going to forget Miya," she said, "and my other daughters thought I had completely lost my mind."

    Billy's cells were shipped to ViaGen Pets, a Texas company that provides the cloning service. With more than $50,000, Must picked up a new puppy. "The dog has a real soul and is everything my daughter was—fun, social and kind," she said. "I feel that I still have that touchable connection and not just a spiritual connection.”

    Cloning animals is hardly new. But the recent news that singer Barbra Streisand had cloned her dog grabbed international headlines. People for the Ethical Treatment of Animals(PETA) president Ingrid Newkirk issued a statement saying she would love to talk her out of cloning, noting that millions of wonderful dogs are getting old in animal shelters every year or dying in terrifying ways when abandoned.

    Normally, a doctor takes a tissue biopsy(组织活检), a piece of skin and muscle about the size of a pencil eraser, from the dog. The next step is to take an egg cell from a donor dog, remove the egg's nucleus, and insert DNA from the pet to be cloned. When an embryo(胚胎)develops, it is transplanted in the body of a mother dog.

    In the basic cloning procedure, scientists take an entire adult cell and put it into an egg that's been relieved of its own DNA. The resulting embryo is a clone. However, in many animals, only one in 100 cloned embryos ever leads to a live birth. Some embryos die in the IVF dish or in the mothers bodies. Of those that are born, a few suffer from abnormalities and quickly die. Besides, pet cloning doesn't mean copying everything of your beloved pets.

    When a laptop or smartphone battery starts losing its power, the only options are to buy an expensive replacement, or just keep it plugged in all the time. But a woman Mya Le Thai may have found the answer to this problem.

    Thai was frustrated that the batteries for her wireless devices degraded(降级)over time, until they failed to charge fully. She did not like having to keep her laptop connected to an electrical outlet to keep it powered on. So, she decided to do something about that problem. At first, she and her team at UC Irvine thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium—ion(锂离子)batteries to last forever.

    Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. Most of these batteries have a life span of about 7,000 charging cycles before they die. One of the reasons lithium—ion batteries degrade is their use of nanowires to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extremely efficient carriers of electricity, which makes them useful in batteries.

    But, Thai had a theory—the nanowires might last longer if covered with a gel(凝胶). She and her team tested this theory. "It was a long process and a lot of work, "Thai said. The team tried many coverings for the wires. PMMA, a type of plastic, was one of them. The nanowires were coated with PMMA and cycled through charges 200, 000 times. The PMMA-coated nanowires showed no evidence of damage. The results suggest that batteries could last forever, without losing charging ability.

    Thai hopes to continue her research to understand why this gel works so well and to see if any other gel could create better results and she is enjoying the publicity about her discovery. She said she never expected her research to get media coverage. "It's kind of cool," she said. "I'm really glad people are showing interest in my work and not just in the work itself, but also in technology and energy."
