Everyone has their own insecurities regardless of how you look or how people perceive you but sometimes people give their insecurities too much power. Defining beauty is simply a matter of opinion. For me real beauty has very little to do with the structure of someone's face or body.
There is no absurdity so palpable but that it may be firmly planted in the human head if you only begin to inculcate it before the age of five by constantly repeating it with an air of great solemnity.
