Never give up but keep walking

During this tough semester, when I performed not well in the exam or got bad grade for my assignment, I always feel depressed and disappointed, sometimes I do not want to do anything about study any more. However, I read lots autobiographies of successful person, and learnt that we should persevere no matter how difficult the situation we are facing. Learning from Marie Curie, Stephen Hawking’s successful experience, I believe that we should never give up for our goal until we reach it.
First of all, Marie Curie was persistent in her research though the research is so hard for her. Since she never gave up her dream, finally she succeeded. Marie Curie, the one of only two people who was honored with Nobel Prizes in two different sciences areas, was a pioneer in the field of radioactivity and she discovered radium and polonium. In 1898, Marie Curie and her husband started the challenging work of separating out radium material. When they made this groundbreaking decision, they admonished themselves that this research would be laborious and difficult. However, they never think of giving up so they kept determined to solve any problem in their research. Actually they didn’t have enough money to work in a good laboratory with precise equipment, so they had to grind pitchblende with a pestle and mortar. They optimistically weighted out a 100-gram sample of pitchblende and believed that they can succeed soon. During the further research, they realized that what they were searching for was present in such minute quantities and so complex the pitchblende was that chemical separation of its constituents was really an arduous task for them. Nevertheless, they were sure they can discover and separate the element from the large number of pitchblende. Spending four years, the couples eventually separated one – tenth of a gram of radium chloride from a ton of pitchblende. Thanks to their persistent, the discovery of radium and polonium found quickly.
Moreover, the example of Stephen Hawking also taught me lots to be insistent for my dream. Stephen Hawking, British theoretical physicist, has come to be thought of as the greatest mind in physics since Albert Einstein. He excels in his amazing research in the field of cosmology and theoretical physics. However, Hawking is severely paralyzed since early adulthood with the degenerative nerve disease, and during a visit Hawking contracted pneumonia, which in his condition was life-threatening as it further restricted his already limited respiratory capacity. As a result, Hawking has been confined to a wheelchair and had lost the use of most of his physical functions; even couldn’t write or speak. Actually, anyone who is been reduced to Hawking’s condition would become gloomy and depressed even committed suicide. It’s a miracle that Hawking thrived on his wheelchair and make world-renowned achievement. Although Hawking appears to speak his great opinion fluently through his electronic voice synthesizer, in reality, creating the text is a tedious drawn-out process that a posed question took 7 minutes to answer. However, Hawking never give up but persists to do further research. Because of his steadfastness, he became one of most successful scientists in the world.
In a conclusion, I do not think anyone’s dilemma can compare to Curie’s or Hawking’s. From these two great scientists’ experience, I firmly believe that no matter how rough the situation we are in, we should not give up but keep working on it, and finally we will succeed. So whatever the difficult situation I am going to be in upcoming four years, I will never give up but keep walking.
