Beauty depends on size as well as symmetry. No very small animal can be beautiful, for looking at it takes so small a portion of time that the impression of it will be confused. Nor can any very large one, for a whole view of it cannot be had at once, and so there will be no unity and completeness.
The epithet beautiful is used by surgeons to describe operations which their patients describe as ghastly, by physicists to describe methods of measurement which leave sentimentalists cold, by lawyers to describe cases which ruin all the parties to them, and by lovers to describe the objects of their infatuation, however unattractive they may appear to the unaffected spectators.
Every beauty and greatness in this world is created by a single thought or emotion inside a man. Every thing we see today, made by past generations, was, before its appearance, a thought in the mind of a man or an impulse in the heart of a woman.
For nature gives to every time and season some beauties of its own; and from morning to night, as from the cradle to the grave, it is but a succession of changes so gentle and easy that we can scarcely mark their progress.
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.
