I firmly believe that there's no such thing as ugly. Although as a spotty youth I would never have agreed with that statement. At the time I firmly believed that I was the ugliest soul in Christendom; in fact I was convinced of it. After all it was why girls never fancied me. It didn't seem to occur to me that the real reason was because I was a shy, charmless nurk.
Ugly is a state of mind, an unnecessary state of mind. No one is ugly, there is beauty in everyone. The secret is to liberate that inner beauty and learn to love yourself. There are no benchmarks for beauty. Beauty cannot be dictated by the media. Beauty, like art, is in the eye of the beholder. If you look in the mirror and see yourself as ugly then you are not looking the right way. Instead imagine you are someone else looking over your shoulder. See yourself in a new light. As others see you. There will always be many who see you as beautiful. Trust that majority and not you the minority.
