How to write a 400-word composition praising classmates' shining points

Today, I want to praise one of my classmates, who is neither tall nor short, with black hair, wise eyes, small nose and smooth tongue. He is my good friend-Dai Zhiyan. He not only studies well, but also cares about his classmates, but what I want to praise here is that he is brave in trying and optimistic.

I remember the day before yesterday in math class, the teacher asked us a math problem, which stumped us. We you look at me, I look at you, I don't know what to do. In this era, knowing the word boldly raises your hand to answer questions, with a loud voice and confidence. When he finished his satisfactory answer, he was told by the teacher that the answer was wrong. Dai Zhiyan was not discouraged after listening, but sat down with a smile and continued to seriously start thinking. But what if it's me? I'm not sure. I dare not take the initiative to answer. If I answer wrong, I will be very depressed and will not be calm for a long time. ...

This bright spot of Dai Zhiyan is worth learning from all of us. Because in life and study, we will inevitably encounter difficulties and setbacks, and we will inevitably come into contact with new things and new environments. If we don't have the courage to try and an optimistic attitude, we will stop in the face of difficulties, fail in the face of setbacks, and lose many opportunities to experience new happiness, broaden our horizons and enhance our new abilities.

Let the bright spot of courage to try, happiness and optimism shine on each of us!
