Ahhh, you make a good point!
Many people often like to say "Focus on the things you like about yourself [whether it's your appearance, personality, etc.] and work on or accept the negatives." But it doesn't seem to work that way in real life, does it? Like you said, an employer could be going down a list of attributes at a job interview and see great things, but then realize you are very timid. They can't have that at their job, they need a PEOPLE PERSON, DAMMIT! Tsk tsk. Shame on your for being introverted, that is a grave and unforgivable, shameful sin.
Seriously. Let's get real, folks - the world wants perfection. They want all positives and no negatives. So you have a pretty face but no chest? Nope, pass (totally not slamming women with small breasts by the way, I don't think there's anything wrong with it - plus some guys like small breasts - but this seems to be the way MANY operate). You're super handsome and have a great job - but you're short? Oh no. Or maybe you're tall and rugged but work at McDonald's. Uh oh.
Haha, okay maybe that was a really bad set of analogies. Sorry. But still, there's a point in there somewhere
