Since it is all self-reported, yes, it matters how you're feeling, what you're doing/thinking, etc. It's like trying to predict what you might dream about :-) But there is no "perfect" score, aiming for zero ain't gonna happen I don't think. Since everything is on a continuum, if you think about it, if you're too "outgoing" it's probably going to imply that you're not "thoughtful" enough, that sort of thing. One wants balance in one's life, not perfection/no problems.
