There was a young man named Jack. He was very smart, but he always felt that he lacked the courage to try new things. He was always afraid of failure, of being rejected, of not looking smart or outstanding enough. One day, Jack met an old man who told him a secret: the reason why he felt that he lacked courage was because he was afraid of failure. The old man told him that failure was the mother of success. Only by experiencing failure could one succeed. Jack was deeply shocked by the old man's words. He began to try new things, no longer afraid of failure. He bravely challenged himself to participate in various competitions and activities. Although he had failed before, he learned from his failures and became stronger. In the end, Jack achieved great success. He became an excellent entrepreneur and owned a successful company. He was grateful that he had listened to the old man's words and tried new things instead of staying in his comfort zone. This story tells us not to be afraid of failure. Only by experiencing failure can we succeed. We should bravely challenge ourselves, constantly learning and practicing to become better ourselves.
