I'm not one for labelling or organising people according to personality, but I do find it interesting how people see and experience themselves.
I notice that a lot of the introversion I come across is a result of underlying problems such as anxiety and shyness, but I feel that anxiety for me has had no real impact on my personality other than the fact that it drives me away from the situations which I feel I would never have went for anyway. I know a lot of people who identify themselves as introverts that work in bars and nightclubs happily, while I after a few months had to quit because of stress. I also know some who would identify as an extrovert with a great desire to communicate and socialise, but are hounded by anxiety to the point where they can't. So my understanding of this would be to say that your personality is more about what you think than what you do.
I have no specific question to ask here, but it would but interesting to hear the community's thoughts on personality traits, how they came about and how they are experienced.
