comparisons

I aspire to be someone, who aspires to be no one. No one can call themselves perfect, perfection doesnt exist. So what is it that we all seek? We all want to improve things about ourselves, but why do we want to improve that button nose or that big ear? What is it that triggers in our minds to say 'this needs to change, its not normal'. Who are we really comparing to? If no one is perfect then there shouldn't be anyone that we look up to or we idolise for their features. Do we compare ourselves to people that don't exist? Do we create a picture in our mind and decide that this is perfection? When you look in the mirror you should see yourself, without having to pick out every single little flaw. But what made that so hard to do?
