I am a high school student. A few days before, one of my very good friend told me that he was going to stop the school. He said that he wanted to start his own business. I tried best to get him to change his mind, but I 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 he should give it a try. The process is more important than the results. Now there is only 60 days left before that test. I am not sure that his decision is right or wrong . I needed your advice.
