Throughout the ages, all successful people have the spirit to try. Edison, the inventor of electric lamp, made more than 8000 attempts to find a suitable material as filament. At the beginning of the experiment, he found 1600 kinds of heat-resistant materials and repeated the experiment for nearly 2000 times. As a result, he found that only platinum was more suitable, but platinum was better than Huang Jingui, which means the experiment failed. Faced with such failure, most people will definitely choose to give up. But he didn't. Instead, he continued to try to find the ideal filament material from plants and tried more than 6,000 kinds of plants. Through constant attempts, Edison finally achieved great success and brought "light" to mankind. This "bright" light is not so much the light of electricity as the light of the spirit of courage to try. In fact, as long as we think about it carefully, we will be surprised to find that among the more than 1000 achievements he has made, there is no one that is not the result of constant attempts. "You get what you try" tells the secret of his success. There are Nobel who developed detonators, lomonosov who discovered the law of thunder and lightning, and the Wright brothers who flew into the sky for the first time ... What amazing achievements did they make that were not the result of hard work?
