How to write a 400-word composition praising yourself

Praise yourself. I think everyone has advantages. Some people are polite, some people love their work, and some people have always been among the best in academic performance ... what about me? Now, let me praise myself! I am a serious and responsible person. I was praised by my teacher for my writing. Teacher Yin, the head teacher, said, "It is most comfortable to correct Wang's homework." The Chinese teacher also wrote "beautiful words" in my exercise book to encourage me. In my opinion, a person's handwriting is just like his appearance. If you write in a mess, others will think that this person must be untidy. On the other hand, if you write neatly, others will think you must be pleasing to the eye. I have another advantage? Of these three subjects, mathematics is the best. There may still be 0.5% talent, but the most important thing is to study hard, be careful and master the basic knowledge. Last year, I won the first prize in the school's "Mathematical Ability Competition". For other subjects, I also try my best to learn. I hope I can get good grades in all aspects. Besides, I am interested in sports because I am more active. I also carefully completed the open-ended homework assigned by the teacher. At the school science and technology festival and foreign language festival, the rocket model and the small sailboat model I made with the help of my parents won the first prize, which won glory for the class. Do you think what I said is commendable?
