Realization?

I am starting to realize/see that people around me and just in general mainly basically care about themselves. This is not directed at anyone, but we all (myself included) tend to worry about what we want, need, or feel will work out the best for us. Of course we should worry about ourselves, but why not everyone? I just thought about this because I am not sure that everyone knows that there are many interpretations of how someone can view something you say or the way you act towards them. Well, I'm done rambling about my crazy thoughts. Guess I'll go talk to a wall. See ya.
