You can’t make everyone happy no matter what. All I can do is live my life and try to be successful and please myself. I have my own morals I live by. Bill Cosby once said, ‘I don’t know the key to success but the key to failure is trying to please everybody.’ I agree with that. I live my life my way. I try to do the right thing, but I know there are going to be people who aren’t happy with what I do or say no matter what, so I’m not going to worry about it.
