Overcoming Obstacles: How Your Biggest Failure Can Lead to Your Success

There’s been a lot written on the theme of failure and how essential it is to success. In a world where 1 is given for people’s accomplishments, failing feels dangerous. The fear of failure can stop people taking risks that might lead to success.

Heidi Grant Halvorson, a psychologist, points out much of success is 2 not on talent but on learning from your mistakes.

About half of the people in the world hold that ability in an area --- be it creative or social skill --- is natural. The other half believes, instead, that someone might have a preference or something --- say painting or speaking foreign languages --- but this ability can be improved through 3 practice or training.

It’s almost impossible to think rationally (理性地) while shouting at yourself, “I’m a failure”. But when you 4 your thinking, you will probably see what you can control --- your behavior, your planning, your reactions --- and change them.

The primary 5 between successful people and unsuccessful people is that the successful people fail more. If you see failure as a monster approaching you, take another look.

Success is as scary as failure. Researchers report that satisfaction grows on challenges. Think about it --- a computer game you can always win is boring; one you can win 6, and with considerable effort, is fun. In pursuit of success, failure exposes areas that you need to 7. So the failure serves as a brick wall to test how you apply yourself to 8 your objectives and how much you want them.

There is a way to distinguish whether a failure 9 you to double down or walk away, says Halvorson. If, when things get rough, you remain fascinated by your goal, you should keep going. If what you’re doing is costing you too much time and energy or it’s not bringing you joy, you should give a second thought to the 10 of your goal and even set a new one.

Death: 12-15-1890

Under him, the Sioux and Cheyenne Nations unified. He was advised to go on a European tour in 1887, but he turned it down to defend these two nations from being separated again. He led his people during years of resistance to United States government policies and was killed by Indian agency police on the Standing Rock Indian Reservation.

Television watching is an activity which is known to be harmful to health and is distinct from getting too little exercise. But a new study suggests its damaging effects may even 1 alongside those from smoking and obesity. Researchers who studied television viewing habits in Australia calculated that people who watch for a(n) 2 of six hours a day shorten their life expectancy by almost five years.

They based their calculations on data on the 3 between television viewing and death from the Australian obesity and lifestyle study which involved l 1,000 adults aged 25 and over. After 4 these findings to the whole population over 25, who are estimated to have watched 9. 8 billion hours of TV in 2008, they concluded that it 5 for 286,000 years of life lost — equivalent to 22 minutes for each, hour watched. By 6, smoking one cigarette is estimated to shorten life expectancy by 11 minutes — equivalent to half an hour of TV watching.

Writing in the British Journal of Sports Medicine, the authors from the University of Queensland, say the figures suggest “huge loss of life may be 7 with too much TV viewing.” The UK and other industrialized countries are likely to be similarly affected “given the typically large amounts of time spent watching TV and the similarities in disease patterns.” The researchers add: “If these figures are 8 and shown to reflect a cause and effect relationship, TV viewing is a public health problem comparable in size to established behavioral risk factors.”

Researchers from Taiwan University found even those who did as little as 92 minutes’ exercise a week, — equivalent to 15 minutes a day for six days a week -- reduced their 9 of death by 14 per cent. Even this small amount of exercise could postpone one in six of all deaths — similar to the effects of a stop-smoking programme. Each 10 15 minutes a day reduced the death rate by a further 4 per cent.

Nowadays, many middle school students are taking all kinds of after-school class. There are two opinions about it. Some think that students can get good exam results and go to better schools if they took these classes. They also believe that students can avoid to watching too much TV or playing computer games by taking more after-school classes. But other think students need more time to rest. If they take too much classes, they might feel stressed-out. Besides, putting too much pressure on them can have the opposite effect. As for me, I don’t think take extra classes is necessary.
