166 cm? That's rather tall, isn't it? Here I am down here at the 160 cm mark! I wonder, are Australians quite tall in general?

In all seriousness, though that was a serious question and I would love to know if Australia is just filled with giant people, good on you. Self-respect is acknowledging that you, and no one, for that matter, can be perfect. It is accepting your "flaws" as part of yourself and as more than "flaws". Every imperfection tells a story-each are one line in an ongoing tale. Honestly, I hesitate to use the word "flaw", as I feel something, in regard to appearance, is only a "flaw" if it poses a threat to your health.
Beauty is gifted to everyone, it is simply up to the individual to accept it. Not an easy thing in a society which scoffs at those who dare tug at the ribbon. So again, good on you.
