The sentence "I can do it" accompanied me to overcome one difficulty after another. I believe that it will grow with me and make me an excellent person in all aspects. The phrase "I can do it" often hangs on my lips and almost becomes my oral talk. No matter in my study or in my daily life, I always say to myself, "I can do it." Once, there was a quiz in mathematics. I passed all the way to the last question. It seeks the volume and surface area of a graph. I calculated it again and again on the toilet paper, but I still can't work out the answer to the question. The score of this question is 8, so don't try to get close to 100. I was so anxious that I was sweating, but the more anxious I was, the more I couldn't figure it out. In a blink of an eye, I had used three pieces of draft paper. Look at the time, there are only 10 minutes left, and I think: this is the end, there is no hope at all. Just then, I remembered the sentence "I can do it". There will be a solution to any problem. I believe I can work it out. I calmed down, carefully analyzed the meaning of the question and carefully drew pictures on the draft. Hey! I figured it out, and it suddenly dawned on me that a difficult problem was so simple. When the teacher handed out the test paper, I said that very few students got the last question right. I was very happy and grateful for the sentence "I can do it". The sentence "I can do it" not only helped me with my study, but also helped me a lot in my daily life. Once again, the sluice on the second floor was broken, so I borrowed water from our house. Mom and dad just went out, and I was doing my homework at home alone. I think: I'm old enough to help my parents. I'll go to the second floor to deliver water alone! I brought a big bucket, filled with tap water and walked to the second floor. I finally came to the stairway, and people were already exhausted and panting. I thought to myself, this is really heavy. Can I carry it? It's better to leave it here and let the people on the second floor pick it up. But there's an old man living in his eighties on the second floor, and his children are away, so it's not convenient to walk. How can he carry water? At this time, I remembered the sentence "I can do it" again. I thought: As long as I work hard, I will succeed! I managed to carry the bucket to the second floor. The old man thanked me and said "thank you". Be confident, I can do it. As long as you work hard, you can do it. If you work hard today, you can do it tomorrow and the day after tomorrow. Others succeed by hard work, and I can do the same by hard work. Ideal, self-confidence and diligence, there is no shortcut to success, step by step. I work hard, I can do it.
