A Person Who changed My life

I have met many people in my life, but a person who changed my life was my art teacher in the university. He and I differed in the terms of appearamce. Not only did he have a bald head, but he also was tall. Moreover, he was fat. Indeed, he was a strong old man.
8 years ago, I went to the art university because I studied sculpture. On my first day in the university, when I arrived at my class, he was standing in front of a blackboard. I was afraid of him because he seemed like a gangster. After my class started, he talked to us about his history. his history was very successful and funny. I was fascinated by his personality.
He was a very strict teacher. One day, when I didn't finish a work of art on time, he said that he hadn't waited for me and I wouldn't exhibit it. I was very sad at that time, but he taught me about artist's way.
In conclusion, after I met him, I kew that the artist's way was strict and interesting. However, I wanted to be an artist. Now I can lead a full life.
