my future is not a dream英文作文

Last term,I got poor marks in maths.I felt very sad.My parents were much worried about me.During the winter holidays,my class teacher came to visit us and talked to my parents about my future.My teacher said,though I was not good at maths,I was good at basketball.My P.E.teacher said I would be a promising basketball player in the future if I tried hard.They encouraged me to study hard in order to be an educated sports man.Now I know clearly what I will be.I said,"I will never lose heart.I will do my best to catch up with my classmates in maths." Now I am making progress in every subject with the help of my teachers.
I'm sure my future is not a dream.
