Dear editor,
I am a high school student. A few days before,one of my very good friend told me that he was going to stop school. He said that he wanted to start his own business. I tried my best to get him change his mind, but failed. I know it is difficult of him to change his mind. He is not doing so good in his studies, yet I want to insist that I give it a try. The process is important than the results. Now there are only 90 days leaving before the test. I am not sure that his decision is right or wrong. I needed your advice.
