My favorite motto is "Nothing is difficult to a willing mind." This is my favorite motto. Because, it gave me confidence when I was depressed, and let me challenge difficulties confidently. On Friday, the math teacher left us a difficult problem to solve at the weekend. On Saturday, I finished my Chinese and English homework, leaving only the problems left by my math teacher. I spread out my exercise book and concentrated on counting. Ten minutes, fifteen minutes, twenty minutes ... an hour passed, and I scratched my scalp and couldn't figure out the answer. I was so depressed that I lay weakly on the table. Mom saw it, came over and touched my head and said, "What's the matter, son?" I looked up at my mother and said, "Mom, the math teacher left a particularly difficult math problem, and I didn't solve it all morning." Mother said meaningfully, "Son, have you forgotten what you said in the second grade?" I also pointed to the crooked Chinese characters I wrote in the second grade, "Nothing is difficult in the world, as long as you are willing to climb." "Mom, I only got 85 points in the Chinese exam." In the second grade, I cried and told my mother. "Son, have you ever heard such a sentence?" I looked at my mother curiously. "Nothing is difficult in the world, as long as you are willing to climb." "My mother touched the back of my head affectionately:" Son, although you didn't do well in this exam, it doesn't mean you won't do well in the future. Work hard! ""hmm. " I dry my tears. I took a big piece of paper and wrote, "Nothing is difficult in the world, as long as you are willing to climb." In the Chinese exam a few days later, I got a good score of 98. When I handed my mother the test paper, her mother smiled. I made a promise at that time: whenever I encounter difficulties in the future, I will look up at these big characters and gain the courage to solve the problem. "Mom, I didn't forget. I know what to do. "I picked up the pen again and calculated meticulously. As time goes by, I'm still solving that difficult problem. Finally, I figured out the answer. "Mom, I figured it out. "I told my mother loudly. Mother said, "My daughter finally succeeded in the challenge." I smiled shyly. It is this that keeps me full of confidence to win. So this famous saying shines in my heart every minute and becomes the motto of my life.
