I personally do not have much to say about that, I guess that it's just how people view you. Being self centered doesn't make you a bad person.
To be honest, I consider myself to be self centered too, so once in a while I try to appreciate what I have been given, and I try to do things to give back.
So hey, why not return the favour to those who have given? It's not that it would hurt ;)
