I see far too many people in this world that make the mistake of attempting to be what they feel others will like. They step outside themselves in an effort to "fit in" and don't convey their true personality. To me this is a recipe for disaster, as you can not really act forever. This comes off as forced behavior and people will see through it.
Your best bet in this life is to just be who you are. No, not everyone will accept you and some times you will even run into to people they may not actually like you. But in all honesty, you may not like them either so what's the difference. Is it really that important to be a part of the crowd? Chameleons have an uncanny knack for blending into their surroundings. I on the other hand want to do no such thing.
I would rather be myself and stick out in the crowd. Just because everyone is not exactly like you doesn't mean that you are less than. If anything it's better to be different because most people really get tired of the same old thing. Besides you might be surprised by the number of people who truly will accept you for who you are. And it's always easier to left the burden of putting on a show.
Being true to ones self has become something of a lost art in this world. We live in a society where what is "normal" is dictated to it's inhabitants on a regular basis and quite frankly there isn't a soul alive today that truly fits the definition of normal. It's not worth the time nor the effort for anyone to attempt to embrace the delicate boundaries of normalcy. Go ahead and be a freak of nature, you'll be happier than you would be with the constant act.
