Edison, who was considered an imbecile in primary school, made such a great contribution to human civilization when he grew up. Many inventions 1000, such as electric light, telephone, tram, phonograph, film, radio, etc., were entirely made by his superhuman research spirit, persistent determination and indomitable efforts.
It is conceivable that 1000 kinds of inventions need great perseverance! However, our Edison made progress despite difficulties and never backed down. He overcame all difficulties with fearless spirit.
Anyone who knows Edison's deeds must know that almost all his life has been devoted to human inventions. He thinks about invention every day, because he knows that this is his job, and he regards creating happiness for mankind as his greatest happiness. Compared with some of us now, we waste time all day, let precious time disappear from our hands bit by bit, and even regret it when we wake up.
Of course, Edison's invention process was not smooth sailing. When he invented the electric lamp and selected filament materials, he screened 1600 kinds of minerals and metals. Because we can't find a suitable filament material, the light bulb can't last for a certain time, which leads many people to criticize and attack Edison, and even call him a "visionary", "liar" and "fool". Edison himself was really hit hard, however, with his love of science, he was not defeated by this. He regained his confidence and continued to study the manufacture of electric lights. After 65,438+03 months of uninterrupted experiments, while excluding minerals and metal substances, he swept over and chose various fibers, such as paper, thread, plant skin and about 6,000 minerals he could think of. After processing, he finally found the most suitable filament product-bamboo in Japan.
"Perseverance is the foundation of success", in fact, from the research process of his doctor alone, we should believe the accuracy of this sentence. It is because of his perseverance that he has achieved his career and made us bright today.
The above example tells us that no matter what we do, we should make unremitting efforts and not be knocked down when we encounter difficulties. But to set a firm goal, cheer up and get up from where you fell. Only in this way can we not show cowardice. We should be as confident in the future as Edison.
