When I meet someone, I'm at a loss for words. "I'm Heather," is usually all I can muster without some sort of prompting. I think people who are proud of themselves, of who they are, can say things like "I'm Annie, and I'm a columnist for the local newspaper and volunteer at Hospice on the weekends. I, on the other hand, am not very proud of myself. I define myself by my failure-- failed writer, failed artist, and perpetual job-hunter. I guess my most honest assessment of myself would be "I'm Heather, and I fail at everything except for knitting."
Still, that doesn't hold true with me either. None of what I just said. Sometimes I try overly-hard to define myself by my creative ability because of my fear of lack of self. For example, if my personality, if who I AM is just a conjunction of brain chemistry, and possibly some sort of cultural subconscious, then I'm no one really. And as plausable as that is to me sometimes, it's a very frightening proposition for my ego.
