In the long river of human life, you can do many things. If you cherish your time in this life, when you are about to pass away, you will not regret doing nothing. The inventor Edison was such a person with no regrets. He said: It doesn't matter whether there is an afterlife or not. Anyway, I have tried my best in my life. Yes, he devoted his 84 years of life to mankind, making our world full of light, comfort and happiness.

Edison, who was considered an imbecile in primary school, made such great contributions to human civilization when he grew up, including more than a thousand inventions such as electric lights, telephones, trams, phonographs, movies, radios, etc. This was achieved entirely due to his superhuman research spirit, perseverance determination, and indomitable efforts.

You can imagine how much perseverance is required to create more than a thousand inventions! But our Edison pushed forward despite difficulties and never flinched. He overcame all difficulties with a fearless spirit.

Anyone who knows Edison’s deeds must know that almost all of his life was dedicated to the cause of human invention. He invented and thought about inventions every day, because he knew that this was his job. He must do it. He regards creating happiness for mankind as his greatest happiness. Compared with some of us now, some people do nothing all day long, wasting their time, letting precious time disappear from their hands little by little, and even regret it when they wake up. and.

Of course, Edison's invention process was not smooth sailing. When he invented the electric light and selected filament materials, he screened more than 1,600 types of minerals and metals. Because they could not find a suitable filament material, the light bulb could not maintain light for a certain period of time, which led many people to criticize and attack Edison, and even called him a "dreamer", "liar", "fool", etc. Edison himself was indeed criticized a lot. A big blow, however, with his love for science, he was not knocked down by this. He regained his confidence and continued to study the production of electric lamps. After 13 months of uninterrupted experiments, while excluding minerals and metal substances, another He chose various fibers, such as paper, thread, plant skins and about 6,000 kinds of minerals that he could think of. After processing, he finally found the most suitable filament product in Japan - bamboo. After repeated experiments, he finally succeeded.

"Persistence is the foundation of success". In fact, judging from his doctor's research process, we should believe the accuracy of this sentence. It is precisely because of perseverance that he achieved success in his career and the light we have today.

The above examples tell us that no matter what we do, we must work hard unremittingly. When we encounter difficulties, we must not be knocked down. Instead, we must set a goal and cheer up. Wherever we fall, we should get up. Only in this way is it not a sign of cowardice. We should be as confident as Edison about the future.
