precious lesson

Every people in the world have up and down in life. Most of them already faced troublesome situation that makes them into a winner or a looser. There is a small difference between being a winner and being a lo0ser. A winner learns and tries to solve his/her problem, but on the other hand a looser stays at that situation and does nothing.
When I was in high school, I often faced this kind of situation, that I had to make a decision, which I was unsure of. At the first time, I didn't want to study so I rarely got good grades on my exam. Despite all that I didn't change my habit. I acted like a looser that I had stayed in that situation without trying to solve it. Until one day, the headmaster asked me to come to her room,than she warned me because of my score. I would not pass the second grades if my score didn't improve. Before, I had never warned like this.I regret that and change my mind, I studies hard and didn't play around anymore.
In the end, I had passed the second grades with good marks. This experience really memorable and important for me.I have learned some precious lesson.there is nothing impossible to be done if we keep on trying.
