Fixed or growth mindset — which do you have?

    We live in an uncertain world with all the technological advances we are experiencing， which meanse is a requirement for a change in midset (思维模式）. In order to be on top of our game both personally and organizationally, we need to develop a growth mindset.

    A fixed mindset supposes that you have native abilities and are naturally clever or skilled in certain areas of life. When you receive infonnation about how you have performed in a test or set of tasks t you may worry about how you are judged. Our parents probably said to us when we were young,"Since you scored really well in the test, you must  be clever." However, by being repeatedly told “You are clever” or “You are really good at your job”，a person's self—respect is actually dainagcd.

    The  growth—mindset  person a view life as a series of exciting challenges and  want  to constantly  learn. Brain activity occurs in this mindset when they receive information about what they could do belter or improve. They do not view their abilities as fixed or us failure. Learning is king and the more they practice , the more they know they will succeed.

    What is important is giving praise around process and not around ability. For example , instead of saying"Since you got a great score, you must be clever" f say " You got a great score, and you must have tried really hard". This creates challenge in individuals and the meaning of mindsets is massive for business. Fixed-mindset managers are not fans of giving feedback (反馈）. They do not want to stretch themselves or others because they fear failure. Therefore their business may stand still because there is no risk or innovation (创新） occurring.

    Listen from your own fixed mindset — for example ," I can't  do that” — and answer with a growth-mindset response — “I can't do that yet!" Remember  there is no such thing as failure and there is s only learning. If you don't fail occasionally ，you will never learn to change and grow.

    Pele was born to a very poor family on October 23, 1940. His real name is Edison Arantes do Nascimento. Pele is just a nickname.

    Pele first learned the game soccer from his father. As a youngster Pele played soccer for a local club. By the time he was 16, he was playing professionally for the Santos Football Club. The club won nine national championships while he played for it.

    Pele also played for Brazil's national team in four World Cups. At his first World Cup in 1958, when he was just 17, Pele scored an amazing six goals. In the final game against Sweden, he scored two goals and Brazil won its first-ever World Cup. Pele also helped Brazil win World Cups in 1962 and 1970.

    Pele had an outstanding(突出) natural ability as a soccer player. He had great speed and balance and was able to shoot powerfully and accurately with either foot and with his head. Many European teams offered huge amounts of money to get Pele to play for their countries but Brazil declared him an official national treasure so he would stay in the country.

    In 1974, Pele retired from the Santos Club, but the next year, he came out of retirement and signed a reported $ 7-million 3-year contact(合同) to play for the New York Cosmos of the North American Soccer League. Pele said he did not this for the money. He said that he wanted to make soccer a truly popular sport in the United States. Millions of North Americans gained a new respect for the game after watching Pele play.

    The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    ⑴How many times did you brush your teeth yesterday?

    Finding: A full 33% of seniors brush their teeth only once a day.

    Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    ⑵How many times did you wash your hands or bathe yesterday?

Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number which doctors recommend.

    Step: We touch our faces around 3,000 times a day-often inviting germs（病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

    ⑶How often do you think about fighting germs?

    Finding: Seniors are not fighting germs as well as they should.

    Step: Do you know it is not your toilet but your kitchen sponge（海绵）that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

    Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport's rules require that a race walker's knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It's this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

    Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

    However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

    As a result, she says, some of the injuries associated with running, such as runner's knee, are uncommon among race walkers. But the sport's strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
