I think it's funny, for a person to judge one's identity solely on his or her outward appearance or the way they present themselves, especially artists or people of the arts.
If you only see the difficulty in being original when everyone else seems to have already made a mark by the way they dress or talk; that no matter what you do you'll always be stepping on somebody's established territory; that originality is non-existent in this day and age; then you haven't discovered the origin of you.
We are all made up of many different parts that may be similar to one another but putting these parts together creates something uniquely you. They key is in finding what really comes out as what you're really about. Not the way you look, nothing about appearance. It's the way you think and act on it, and not giving a hoot about what others might say because you know yourself better. You dress what you think, not think what you dress. This is not about putting up a show to impress, it's about being originally you.
When you doubt yourself from what others say about you, then it means you're not strong enough to carry on with being yourself. Life is not an effort to please others or to garner some form of attention, to be liked and popular and whatever that comes with it. Life is a struggle in being content and at peace with yourself and your Creator, the One that knows you the best.
So, don't tell me originality is a lie, it only means that all this while you've been measuring yourself through others, it is futile. Try measuring the sky with a matchstick.
