I disagree . . . it's not "hopeless" . . . If you WANT to change something about your personality, like being sociable, then you can change and be more sociable, but it takes practice.

I'm assumming you are an introvert. There's nothing wrong with being an introvert.

Sometimes be sociable is no different than public speaking or dancing or teaching. They are all just roles played. So you prefer wearing certain hats? It doesn't make you a "misfit" . . . it's called being an individual and it's what diversity is all about.
