An example of inspirational and successful persistence.

Kepler, a German astronomer, was troubled since he was a child. He came to the earth early in his mother's womb for only seven months. Later, smallpox made him grow acne pits, and scarlet fever damaged his eyes. However, with his tenacious character, he studied hard and his academic performance was far ahead of his peers. Later, because my father was in debt and lost the opportunity to study, I taught myself astronomy. In his later life, he experienced a series of blows, such as illness, the death of his mentor and the death of his wife. But he still didn't stop studying astronomy, and finally discovered the three laws of celestial bodies at the age of 59. He turned all his misfortunes into a driving force to push himself forward, won the title of science with amazing perseverance and became a "man with indomitable spirit."

2. American inventor Edison

Edison failed many times when he invented the electric light bulb. When he used 1000 materials as filament, his assistant said to him, "You failed 1000 times, and your success became slim. Give up! " But Edison said, "So far, my harvest is not bad. At least I found that there are more than 1000 materials that cannot be used as filaments. " After more than 6,000 experiments, he finally succeeded.

I can imagine what would happen to us now if Edison gave up when his assistant advised him to stop the experiment. Maybe we need to light an oil lamp the size of a bean to light it at night. In fact, every failure of Edison's experiment can be regarded as a setback. In this way, Edison encountered more than 6000 setbacks in inventing the electric light, which is an amazing number!
