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 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 I 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. .
