Not only is it self evident you have that quality, but whatever it is, attractive, hot, good looking, funny, classy, kind, smart, confident, cute, good friend, all those are attributes other people ascribe to you, they are meaningless when you direct them to yourself. You don't go up to other people and tell them "look how attractive I am", other people go up to you and say "holy shit, you look good". That's how it works. I know there are self-help books that teach you to tell yourself that until you start believing it as a way to build confidence or whatever, but in private, not to the whole world. This is just tasteless attention whoring and echo chamber validation seeking.
