    Success seems to be what everyone longs for in life no matter how old he is. Students want to succeed at study. Adults look forward to their success at work. Have you ever wondered what is the key to success? Some may say the answer is good luck. Some may say hard work is the key. In fact, hard work really does pay off. Scientists find that perseverance(坚持不解) leads to better grades and higher achievements in school.

“Being passionate(热情的) is not enough to make sure that you can achieve success in your schoolwork,” say researchers, and they thought of “courage” as a key to success. Courage is also considered as effort in reaching long-term goals, and a strong will to continue one’s efforts no matter what difficulties they might go through.

Researchers think that the finding could help create new training to help children develop the skill and help them to succeed in their future.

Researchers from the Academy of Finland studied more than 2,000 students from Helsinki. They were followed through their learning from 12 to 16, the sixth grade until the ninth grade in local school years. Researchers found that the factor(因素) that best predicts courage was related to goals. What they had achieved in their past learning played no role in developing the skill.

Professor Katariina Salmela-Aro, who led the study, said, “Courage means a young person is really interested in his or her studies and does not give up easily. A key factor of courage is high perseverance when facing difficulties or in a terrible situation. The important finding is that these factors are the key to success and well-being. Our study shows the power of courage.”

Professor Salmela-Aro also thinks it is important to develop new practices and build character to improve courage in teenagers. She added, “Young people should see everyday school work as part of their life in a wider context(背景) and set achievable goals for themselves. Schools must also serve as a place where it is safe to fail and learn to deal with setbacks. One must not be discouraged by setbacks, but draw power and new energy from them!”
