Sadness

I felt sad due to low mark for my minor course. What can I do ?, I can not change it. The only thing I can do is follow my teacher's instruction that is don't stress that thing so hardly. Everything happens got reason. I just can do is work very hard for my final exam. Remember, process is more important than result. It's just a little point within my life. Because I have long way to go. Indeed, I am releasing my sadness..
