Dear editor I am a high school sudent 开头的 短文改错.

短文改错？ Just a few days before , one of my close friend told me that he was going to stop the school .he said that he wanted to start his own business , I tried my best to get him change his mind ,but i failed 。i know it's difficult for him to go on with his studies because he isn't doing so good at them , i insisted that he have a trying . the process is more important than the result , now there are only ninety days left before the examination, i am not sure that his decision is right or wrong , i really needed your advice
