Everyone has an experience they would rather forget. Some are embarrassing, some are moving, and some teach us a lesson. Here is a story of mine.
Last Sunday I went fishing. After setting up my fishing rod（钓鱼竿） with bait（鱼饵）, I sat down on the bank of the lake. But two hours later, I didn’t catch any fish. I got very angry and began to pack up my stuff, preparing to go back home.
Just then, I saw an old man sitting near me. To my surprise, his basket was full of fish, so I went over to him, wanting to know why. “Excuse me, but how long have you sat here?” I asked. “About four hours,” he answered. “Four hours?” I could not believe my ears. “Yes. It’s very important to be patient,” the old man said. “Don’t consider fishing a tiring sport. Just enjoy it.” Suddenly, I understand what he said. I must learn to be patient. Then I sat there and waited for fish patiently. I felt a fish touch the bait, but I didn’t move and waited for the right moment to reel it in（卷收钓鱼线）. At last, I caught it. This made me very happy. In the following six hours, I caught over 10 fish.
On my way home, I thought what had happened on the bank. I gradually realized that the secret of success was patience.不唯一
