introverts

i taught i was an extrovert last time, saying things without caring much about how other's felt.
now i begin to assume too much, to take things in a very negative light... like.. the worst possible senario a person could respond to something i said...

sigh..

how do intoverts go thorugh interviews?
isn't it not fair that one has to go through something the is set so much for extroverts?

maybe i'm just cowardly.
