What is an American?

I guess the simplest way to decide if someone is American or not, is to compare their lifestyle amongst other Americans. By this standard most anyone can "be" American but with such a diverse country and its many cultures, is it even possible to find a standard to judge against? I live in America, as was I born here, but I don't consider myself anymore American than anyone else. I am not political, I find the majority of the country is struggling with obesity, and with all of the fast food monopolies running the market, it's not easy to get from overweight to a healthy fitness level. I find that other countries in the world have superb living standards, and even more interesting cultures. Would that make me unpatriotic then? American is a point of view, no matter what the skin color or ethnicity, it is determined by the frame of mind that people view this country and the actions that they take to secure a good lifestyle. People come here to live the American dream as they say. I consider it to be the dream of everyone, it's ignorant to think that only America can provide happiness. It supposedly has a greater opportunity for success that's all.
