雅思口语P2 Describe a time when you learned from a mistake you have made(文字版）

Mention about the topic, a time that I was late for an important examination comes to my mind. Last year, I worked hard on a very important exam and it has got to do something with my future job. I spent 4 to 5 hours each day on it. When the day came, I was late because I couldn't get up early on that morning, or I wasn't on time and I did this quite often. It was a bad habit of mine. I know it. I remembered that was a winter morning when I wasn't allowed to take part in the exam, I was totally shocked and felt… it was hard to say, you know. I was walking around the campus, thinking about what I have done. It was the first time that I realised the importance of procrastination. I hated it. Till now, through the bad experience that I have suffered, I have made the change. I am a morning person I can say. That is it.
