Why Change Anything About Yourself?

Why would anyone want to change anything about themselves? Is it because from a very young age a child is taught that beauty is one of the most important things. Well beauty is not that important! If someone only likes you for your looks and not your true personality then that person does not deserve to be around you. You can never be to skinny or too fat, it doesn't matter what other people think of you, don't change anything about yourself because it only really maters what you think of yourself. (:
