It's not worth it to go after chicks who are too hot for you, if that's what you mean. But it is a good idea to improve how hot you are. Once you get it right, you can basically have any hot chick, because they all think exactly the same. The problem is when you get that "one girl" who you think for some reason is an exception and who you think likes you more than the others. She doesn't. They never like you that much more than an equally hot girl in another state would.
