My good and bad points

I have many bad points. I think my worst is lazy. I have already been absent from a lot of classes, for example, English1, Christianity, international law, or etc. This is my character that I had better improve because it will have some negative impacts to myself in my future. Honestly speaking, I think that lately I have done anything I want to do but haven't done something I don't want to do. When I also was a high school student I was so. I know I must improve this weak point of mine, so in the second half, I will try to become a stable man.
However I think I also have some good points. The best point probably is to be severe to morality. If I find someone strange bothering other I almost warn the person. My friends say to me that it is unexpected, but because I dislike bothering other, I usually do so.
Anyway, I must improve my worst point, lazy....
