Something must be done

After read this I feel so sorry about what I was done ..>_<..
Team work is very important for a business.Cooperation is a key point for a business.I know that.And by doing team work the manager can easily know who has the ability to be a natural leaders or born socialites also easily to know who is shy and who make the work slow down. So we can say that is as same as our classes.Each class is a team and people in class just like working together.And the teacher is like the manager who can identify students good or not.
I also know that if someone is doing nothing at all will make all the class slow down.To be a person there is no reason to affect other people .If you do that mean you are so bad . I have known that. And before I didn't notice that I already affect others.Now I am a bad student not just bad on my study also bad on my behaviour.I do a apology to everyone. A very strong voice in my heart says: siyi you can't do like that anymore If you continue do like that none will forgive you, you will be abandoned. I don't want to be that anymore really.I will be after what I have missed.I will have something be done soon.A big advancement.
Something must be done .Some real thing must be done . A lots of thing I haven't done and they are waiting for me . Come On Something must be done by me ! I am facing some challenge now ... The first thing is beat myself!I will treat my work seriously from now on.
There are something must be done.I will become better and better.I will prove I am nota hopeless person.
