“Cleverness is a gift while kindness is a choice. Gifts are easy – they're given after all. Choices can be hard.” –– Jeff Bezos.

    I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I'd never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I'd been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't, and I wasn't sure what to expect. MacKenzie told me I should go for it. As a young boy, I'd been a garage inventor. I'd always wanted to be an inventor, and she wanted me to follow my passion.

    I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn't already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but ultimately, I decided I had to give it a shot. I didn't think I'd regret trying and failing. And I suspected I would always be haunted by a decision to not try at all.

    After much consideration, I took the less safe path to follow my passion, and I'm proud of that choice. For all of us, in the end, we are our choices.

    Listed below are the stories of women you may not know about, but definitely should.

    Hedy Lamarr

    Hedy Lamarr starred in many films. But her film career is far from her only noteworthy achievement; she was also a brilliant inventor. In 1942, she and composer George Antheil received a patent（专利）for a device that could change radio signal frequencies. The purpose of the technology was to keep military enemies from figuring out messages. But it did more than that - it laid a foundation for the wireless technology we use today.

    Maria Sibylla Merian

    Today, children can happily explain how a caterpillar（毛虫） tums into a butterfly. But there was a time when no one knew this. Until the 1670s, scientists thought that caterpillars and butterflies were two totally different creatures. Thanks to Maria, we know the truth about these beautiful winged insects. Fascinated by insects, she began collecting, studying and drawing them as a child. It was through her study of caterpillars that she discovered the truth about their life cycles. She published two volumes of naturalist research, which provide major contributions to the field of entomology（昆虫学）.

    Ada Lovelace

    Ada Lovelace, the daughter of celebrated British poet Lord Byron, wasn't a poet herself but the world's first computer programmer. We think of computers as a recent invention, but people were toying with the idea of "computing machines" in the mid – 19th century when Lovelace was alive. Lovelace's mathematical genius was apparent at a young age and caught the attention of Cambridge professor Charles Babbage, who was working to design early computing machines that would be able to quickly solve math problems. Lovelace wrote some suggestions as to how to program the machines to work out numbers.

    In addition to designing this early computer program, she was also the first to surest that these computers might be able to do more than compute. She imagined them doing almost everything, from producing images to composing music.

    We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.

    A brain can also simply be a smart person. If a person is called brainy, he is smart and intelligent. If a family has many children but one of them is super smart, you could say, “He's the brains in the family.” And if you are the brains behind something, you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.

    Brain trust is a group of experts who give advice. Word experts say the phrase “brain trust” became popular when Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues（问题）facing the U.S. These professors were called his “brain trust”.

    These ways we use the word “brain” all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word “drain”. As a verb, to drain means to remove something by letting it flew away. So a brain drain may sound like a disease where the brain flows out of the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.

    However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.

    If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make some accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.

    A new report says living in a city makes it harder for people to concentrate(集中) on some tasks. The research found that people who live in rural areas can focus better than people in urban areas. The study is from Goldsmiths College, which is part of the University of London. Head researcher Dr. Karina Linnell and her team made great contributions. They studied how two groups of people did the same "thinking tasks". The team went to a remote(偏远的) part of Namibia, southwest Africa, to study the Himba tribe. Himba people live a very basic life in the desert. They are still doing traditional farming. The team also studied members of the same tribe who had moved to the nearest town. Dr. Linnell said the tribe who lived in the desert did much better on the tests than those in the town. It's really interesting and shocking.

    Dr. Linnell said their research may lead to changes in the way companies operate. In the future, workers may move from cities to live and work in the countryside. Linnell said there are too many things around us in the city that stop us from thinking about one thing for a long time. This means we do not work at our best. She asked, "What if, for example, companies realized certain tasks would be better carried out by employees based outside of the urban environment? There their concentration ability is better. "The past century has seen billions of people move from the countryside to big cities. In the future, the trend may not continue. If Dr. Linnell's research is true, this century might see many of those people return to the great outdoors. Let's wait to see what will happen.

    Jack London, one of America's major writers of adventure tales, was born in California in 1876. During his life, London worked at many jobs. His broad life experiences would become the background for his writing.

    London loved to read. As a teenager, he spent many hours educating himself at the Oakland, California, public library. He attended college at the University of California at Berkeley, but he stayed for only six months. He thought Berkeley was “not lively enough” and wanted to do something more exciting.

    London wrote stories about working people and the hard times they had making a living. He knew their problems first hand. He worked as a sailor, farmer, factory employee, railroad worker, and gold prospector, to name just a few of his many jobs.

    London grew up near the waterfront in Oakland. He loved the water. When he was fifteen years old, he bought a small sailboat called a sloop. Later he sailed to Japan on a schooner, which is a much larger sailing boat. Like many people of the time, London caught the Klondike Gold Rush Fever. In 1897, he headed for Alaska. He didn't find gold, but he discovered something even more valuable. He discovered that people enjoyed listening to the stories he made up with his vivid imagination. London entertained the miners with story after story. Later, using his experiences during the Gold Rush, he created many more colorful stories.

    London resolved to live a full, exciting life. He once said, “I would rather be a superb meteor(流星), every atom of me in magnificent glow, than a sleepy and permanent planet.” Each day, he pushed himself. Once London determined that he was going to be a writer, nothing could stop him. His goal was to write at least one thousand words every day. He refused to stop even when he was sick. In eighteen years, the writer published fifty-one books and hundreds of articles. He was the best-selling and highest-paid author of his day. Many people also considered him to be the best writer. White Fang and The Call of the Wild are his most famous stories and are about surviving in the Alaskan wilderness. Readers can enjoy Jack London's energy and his talent for telling wonderful stories each time they open one of his novels.
