A human being is a part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feeling as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.
Because of something told under the famished horn
Of the hunter's moon, that hung between the night and the day,
To dream of women whose beauty was folded in dismay,
Even in an old story, is a burden not to be borne.
Remember how in that communion only, beholding beauty with the eye of the mind, he will be enabled to bring forth, not images of beauty, but realities (for he has hold not of an image but of a reality), and bringing forth and nourishing true virtue to become the friend of God and be immortal, if mortal man may.
I think no matter what you look like, the key is to first of all be happy with yourself. And then you know if you want to try to improve things that you don't like about yourself, then do it after your appreciate yourself.
