Bad habits

I am writing to tell you about my old bad habits. I used to drive fast and my parents were advice me but I didn't interested enough. Last week, a policeman came to our college and he told us about accidents and fast driving. After that, I decided to leave this bad habit and drive slow with traffic rules. Also, I used to cheat when I was in secondary school because exams were too difficult. I didn’t use to help people because I didn’t care about them, but one day some thing happened and it changed my life after that I decided to help people.
