Is it worth it?

I have decided that some things are just not worth the trouble. Things like getting angry when someone does something stupid or when someone wants to argue about something and they won't drop the subject. There was one time we had just gotten our yearbooks and my friend "Sara" threw mine on the floor to be funny. It was a nice one and when she threw it on the floor it slid and got little gash marks all over the cover. I wasn't happy and I think she knew it. We had been waiting to do something and afterwards she apologized and I told her it was ok. She was like, "Really? I thought you'd be mad at me." I told her that it was pointless to get mad because one it was just a yearbook and two it wouldn't help anyone. I think I surprised her and maybe influenced her view on being mad a little bit. In my opinion being mad makes you feel better for a little while but in the long run it helps no one. Another thing that I don't think is worth any one's time is drama. I know that in high school and very much in middle school it's almost unavoidable but when you grow up and become an adult IT IS NOT NECESSARY. Why can't we all act like human beings and solve something in a mature way? In conclusion I have many more opinions about what is not worth the trouble but  who wants to read a 5 page paper?
