At the age of nine, I was taking swimming lessons at a pool. The day arrived when I was to be tested to see if I could 1 to a higher level class.

Fifteen of us were to 2 swimming from one side of the pool to the other and back. I watched as my 3, one by one, tried and failed. Then it was my turn to 4, I mean, my turn to try to pass the test. It was about halfway when I got 5. I immediately stopped and 6 the side of the pool, ending my test. Our instructor, a college student, was standing above me. "Why did you7?" he asked, in a less than 8 voice. "I got water in my nose," I 9.

That's when this college student 10 me one of life's great lessons, 11 he probably never realized that. Bending down, he shouted, "So?"

"So?" The 12 shocked me. It had just seemed 13 to me that the answer to pain was to remove the thing causing the 14. My nine-year-old brain had not understood the fact that a valuable 15 is worth achieving, however difficult to get there. Recognizing that, I was 16 nothing would keep me from completing the test. In fact, I did it rather 17 on my next attempt. Seeing me 18 the test, almost all the others did so as well.

Life is a journey, and the road won't 19 be easy. We have to focus on the final destination, not the 20 along the road.

Cycling is a good form of sports, here are some tips on how to do it safely and comfortably.

. Pushing with the wrong part of the foot can raise your risk of developing a painful injury of the heel, says Rob Werstine, a sports physiotherapist (理疗师) and board member of the Canadian Physiotherapy Association. You should push with the ball of your foot, he says.

Put on clothes. While it's warm, wear layers of clothing, with clothing close to the body that breathes and outer layers that do not absorb water..

Be reasonable.  , don't sign up for a 50-kilometre ride. And while cycling is great exercise for people who want to get into shape, if your doctor advises you not to do tiring exercise, cycling shouldn't be your starting position. Werstine says. Walk to begin getting into shape and then graduate to cycling.

Fix the fit. If you develop lower back pain or numbness in your hands and fingers from cycling, it could because your bike isn't adjusted properly for your height.  , but if you have continuing problems, consider consulting a bike fit physiotherapist, Werstine says.

Be mindful. You have to pay attention on the roads to vehicles, other cyclists and pedestrians. . Or do some reading about how to avoid dangerous cycling situations, bicycle safe.com, for instance, listing 10 types of car-bike accidents and how to avoid them.

From self-driving cars to carebots (care +robots) for elderly people, rapid development in technology has long represented a possible threat (威胁) to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2025 as artificial intelligence (AI) continues to change businesses.

"The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces," said Peter Andrew, Director of Workplace Strategy for CBRE Asia-Pacific. A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.

The report is based on interviews with 200 experts, business leaders and young people from Asia-Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates. But the report states, "Losing occupations does not necessarily mean losing jobs—just changing what people do." Growth in new jobs could occur as much, according to the research. "The growth of companies that have the speed and technological know-how will directly challenge big companies," it states.

A 2014 report by Pew Research found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured "a future in which robots do not take the place of more jobs than they create," according to Aaron Smith, the report's co-author.

"Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs. There is no shortage of things that need to be done and that will not change," Microsoft's Jonathan Grudin told researchers.

Rob Kalin learned the secret to success while he was young. As a young child, he liked playing with a stuffed rabbit his mother had made. "At that time, we knew he would become a craftsman (工匠) in the future," Kalin's mother said.

Kalin's father was a carpenter (木匠) and taught him early on how to use his hands. In high school, Kalin was so interested in photography that he cut classes to take photos 18 hours a day. Eventually, Kalin ended up at New York University, studying classics and working as a carpenter. One night, his landlord asked him to build a website for his restaurant. "I didn't know anything about websites, but I built the basic site by looking through books in four weeks," Kalin recalls.

After working on a crafts site that provided "advice and a lot of hand-holding", Kalin recognized that there was no market for their goods. He wrote a fan letter to Stewart Butterfield, the founder of Flickr, who had sold his highly popular photo-sharing website to Yahoo! Impressed by Kalin's letter, he took a look at

 Kalin's idea and invited him to San Francisco for a month in 2006. He taught Kalin how to build a website, and helped him borrow $615,000 from a bank.

 With the help of Stewart, Kalin was able to create etsy.com, an online crafts fair that may be the largest market for handmade goods in the world. Last year, 350,000 woodworkers, and other craftsmen sold their one-of-a-kind goods on the four-year-old site. It sells everything from hand-knitted T-shirts to wooden electric guitars. In an age of chain stores and malls, it seems there's still a big market for the unique: custom-made (订制的) skirts and hand-painted tea sets. Today, Etsy's staff has increased to 70 employees, and more than three million consumers in 150 countries are buying goods on Etsy every year.
