Famous scientist Thomas Edison once said, “Failure is the mother of success.” It means setbacks and defeats eventually lead to success. In other words, don’t be frustrated by failures and continue to do one’s best until one achieves triumph. Many inventions and experiments are derived from lots of trials and failures. Wright brothers, who invented the airplane for the first time, also failed many times before accomplishing their goals. Experiencing failures and making mistakes are necessary to achieve success because failures and mistakes provide learning opportunities, give new perspectives and improve one’s persistence. I will discuss these points and some examples in this essay. First, mistakes and failures are learning opportunities. They provide valuable information on what went wrong and what should be avoided in the future. For example, Thomas Edison experienced lots of failures to make a light bulb, which was his best invention. Thomas Edison was quoted to have said, “I have not failed. I successfully discovered 10,000 ways that don’t work.” (Tavris & Aronson, 2007). Like this example, after making mistakes, people who have a positive attitude towards failing tend to concentrate on their work to get it right. A research was conducted in 2011 regarding this topic. People who think that making mistakes are helpful have a contrasting neurological reaction when compared with people who think that mistakes are not necessary. Therefore, they become aware of their mistakes
