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.

    A cellphone is one of the few things that we hold close to our faces all the time, and yet it could possibly explode - this is what made the recent Samsung's Galaxy Note 7 smart-phone accidents so shocking.

   According to technology news website The Verge, flawed（有瑕疵的）phone batteries might be to blame.

    Even if you are not a science student, you probably know that it is common sense that the anode (the negative（负的）end of the battery) and the cathode (the positive end) should never touch. If they do, the battery will short-circuit（短路）, causing a powerful electrical reaction that can destroy the battery and cause a fire.

    This is why all lithium-ion（锂离子）batteries - the kind that can be found in many of our devices like tablets and cameras - have a separator layer inside to stop the two ends from touching one another.

    But somehow, the separators in some of the Samsung phones broke, causing explosions.

    Overcharging is another problem that can make batteries heat up quickly. Fortunately, most batteries are designed to be able to automatically stop charging once they are fully charged. But again, this somehow failed to happen in some of the Samsung phones.

    The two “somehows” may sound random（随机的）and hard to explain. But they actually both come from the fact that phone producers have been pushing the limits of batteries to meet customers' demand for a longer battery life.

    According to Lynden Archer, a materials scientist at Cornell University, US, we have already achieved 90 percent of the battery life possible from a lithium-ion battery. Customers' demand that their devices get thinner has also given producers little choice but to try to put more power into thinner batteries.

     “The more energy you put into a box, the more dangerous it's going to be,” Billy Wu, a lecturer at Imperial College London, told The Guardian.

    A thinner battery also means producers have to use thinner material for separators, and thinner material has more chance of breaking.

    Are you interested in students in other countries: Do they also have so much homework like you?What do they do in their spare time?

    On April 8,a report came out on the lives of high school students in China,Japan,South Korea and the US.It surveyedaround 6,200 students from the four countries last year.You will find the answers to many of your questions in this report.

    Who study hardest?

    Chinese students spend the most time studying.Nearly half of Chinese students(48.6%) spend more than two hours on their homework every day.That's much more than students of the US(26.4%),Japan(8.2%) and South Korea (5.2%).

    Who sleep most often in class?

    Japanese students fall asleep in class most often.About 45% of them said they sometimes sleep in class.In South Korea,it's 32%;in the US,21%;and 5% in China.

    Who are the most distracted（分心的）?

    American students are the most active in class,but also the most distracted.64.2% said they chat with friends in class;46.9% said they eat snacks in class;and 38.9% said they send emails or read storybooks in class.

    What do they do after school?

    In their spare time,most Chinese students study or surf the Internet.Most American students go out to play with their friends.Most Japanese students do physical exercise.Most Korean students watch TV.

    Indian-origin Anvitha Vijay has given a new meaning to the phrase “age is just a number”; she has proved that achievements and knowledge follow passion and not just age and experience.

    Vijay, who lives with her parents in Melbourne, Australia, at the age of seven realized that her piggy bank did not have enough money to hire a developer to make her an app, so she decided to teach herself how to code. With the help of YouTube videos, the young techie learned to code. For one entire year, she watched multiple coding tutorials on the web and became a programmer herself.

    Vijay's inspiration for developing the apps was her little sister, who was still learning to talk. Therefore, Vijay developed an educational app for children that were her sister's age. The app is called Smartkins, which uses about 100 sounds and flashcards of different animals that help children learn and identify. Later, Vijay developed a similar iOS app for children to identify and learn colors. Each app has been downloaded thousands of times.

    Anvitha's skills won her a scholarship to attend a big tech conference hosted by Apple in San Francisco, California. There, she got tips from the pros. She went to workshops where she learned about the latest software for app building.

    All that training led to an idea for a third app. This one, called GoalsHi, inspires kids to practice good habits. Users are rewarded for achieving goals, such as eating their vegetables or practicing piano. Anvitha says the rewards are like getting a sticker for a job well done.

    Anvitha's goal is to continue creating technology that helps kids learn while having fun. But even more important to her is that the world sees the power of technology in kids' hands. “The more training we get in tech at an early age,” she says, “the better chance we have of becoming creativity champions who will one day change the world.”
