Throughout history, human beings have invented equipment that has made our lives much easier. Have you ever wondered whether you could live without lights at night? Famous inventors usually failed countless times before succeeding, which means the world would be a lot different without success after failure. At first, Edison was a failure when he was young. He couldn’t go to school because he made a lot of mistakes such as trying to hatch chicks, giving a dangerous drug to a friend, and other bad things. He was withdrawn from school. When he invented the light bulb he failed a lot during his experiments. Now, we remember Edison as an inventor of the light bulb. Secondly, think about the Wright brothers. They failed many times before accomplishing the dream of humans flying in the air like a bird. If they gave up after a few failures, we couldn’t travel overseas with airplanes. Finally, we use computers for many purposes. Modern computers are a technological revolution, but they used to be really huge. The computer became a portable device after a lot of development after failing a lot of tests. In conclusion, we have invented many things after a lot of failure. If we didn’t try, we would be like an isolated tribe on an island where human life is pretty different compared to our modern society. Failure is one of the key parts of the process for many great inventions.
