Unperfect Person

I've been doing a lot of looking in the mirror lately. No, I'm not conceited. I have just been trying to determine why it is so difficult for me to meet new people. I have only 1 close friend and no perspective mates. I'm beginning to think I have the word "BITCH" stamped somewhere on my forehead. It is pretty upsetting when I am out and about with my only friend and people speak to her and not me. Now, I am speaking about people in general but the really problem, of course, is the lack of attention I get from the opposite sex. If one takes a moment and looks for rings you can tell that she is obviously married. I, on the other hand, am woefully single.
Does it boil down to looks? I don't think so. Neither of us are skinny, nor is one better looking than the other. Do clothes matter? Normally when we are out and about I am dressed from work (jeans and a nice shirt). She, on the other hand, is a stay at home mom who is usually wearing whatever happens to be clean. So obviously it must come down to personality.
I am starting an experiment. I have a jar that I am going to take around and I am having people put a word or two in the jar that they think describes me. This is going to be completely anonymous so hopefully I'll get some real candid answers.
The effects of my personality have been bothering me lately. In the past month I have been told my sarcasm comes off as bitchy-ness and my shyness comes off as stand-off-ish. The goal of this experiment is to get some more negative personality traits that I can (hopefully) change.
I have wrestled with the thought of changing my personality for sometime now. It is not an easy concept to comprehend. Your personality, for the most part, defines who you are. Changing would be a BIG step outside of my comfort zone. Still, as Einstein said it, insanity is doing the same thing over and over again but expecting a different result. Since I don't like the results of my personality I suppose it's time to change.
I'll conduct this experiment for a few days and then I'll post the results.... Stay tuned.....
