Happiness comes from persistence. I am a happy person, because I know how to persist. In the dreary summer, the earth was scorched by the scorching sun, the original green trees were lying on their backs, and the goldfish in the water were stiffly foaming. Sitting at my desk, turning over my pen and looking at a long and annoying string of arithmetic in the book, I really want to escape. In front of me, I seem to feel the blood flowing back. I've been sitting at my desk for a long time, but I still have no idea. I almost collapsed. The creaking fan on the table repeats simple machine movements. Its fan blades turned and turned, and I saw it waving to me like a Buddha and saying, "Give up, you can't." I hesitated and looked back at those mathematical formulas and geometric patterns. They bared their teeth like devils and grinned at me. At that moment, I really wanted to give up. However, just as I was about to put down my pen, I suddenly found a bug. I picked up the nib and teased it again. It doesn't know where to go in a hurry and keeps climbing. I put it back in its place, but it kept moving towards its goal. When I brought it back again, it worked tirelessly like a "robot". Seeing such hard work, I seem to be infected and my fighting spirit is rekindled. Suddenly I caught a glimpse of a sentence posted on my desk, "Persistence is the most important thing in life!" It suddenly occurred to me that I solemnly wrote and posted this myself. Looking at the tender words, a flame rises in my heart-persistence! I should insist! The pen is my weapon and the title is my enemy! As time goes by, I realize that every minute is important! After several calculations and failures, I insisted again and again, and I didn't know that sweat soaked my clothes. The pen is dancing fast in my hand, I think.

Happiness comes from persistence.

Let these problems be defeated! "insist!" I shouted to myself several times, and the idea of success became more and more firm in my heart. I am a person who can't give up! The second hand seems to be racing with me, while I am competing with the topic. Finally, at that moment, I wrote the final answer smartly. I put down my pen, took a long breath and picked up my homework. Now formula and geometry seem to say to me gently, "You finally defeated us and yourself." I immediately smiled, laughing so brilliantly that the breath of happiness spread. I smile proudly, because I am a happy person, a person who knows how to persist, and this is fast.
