All my life is failure.

It has been a long time I write articles here since July 20th. July 21st was the teacher's test. It's very important to me, but I still failed AGAIN. Yes, again. What's the following? I have no idea. I really don't know what to do. It seems that no matter how hard I work, whatever I still can't do. All my life is failure. That's what I can say.
