Lincoln, the president of the United States, was once a person with a severe stutter. When he was running for the presidency, he was ridiculed many times and lost many times. But he was unwilling to succumb to fate, and he gave speeches and lobbied all over the country to accumulate experience. After many failures, he was elected. Failure is also an important part of life. As the saying goes, "failure is the mother of success." Without this failure, there would be no better success next time. Success is certainly to be celebrated, but failure is not to be sad. When there is failure, there must be success. Success and failure always coexist.
