Introvert VS Extrovert
I voted Introverted, but honestly that's only in regards to RL interactions.
When it comes to online I try to involve myself everywhere, so I consider myself very Extroverted in that sense.
And when it comes to RL interactions, the introverted isn't even any *desire* to be alone.
I love hanging out with people, it's rare to find a time I don't want to.
It's just that naturally, friends are usually busy so I often end up spending a lot of time at home.
That, and even though I do love social interaction, I don't lose anything by being alone. I don't have some itch nagging me for not doing so like Extroverts do.
Socializing is just a nice treat/bonus for me.
Optimist VS Pessimist
I voted Pessimist, but that's because I adopt a "Hope for the best, prepare for the worst" idea.
More accurately I would describe my perspective as "Realist", but it wasn't an option.
So although I do always hope for the best, I prepare for and expect the worst as a safety precaution.
And ultimately I ended up to vote Pessimist there because that's what I'm actually acting on and reasoning on.
I mean, obviously I want things to go well, every pessimist does. But it doesn't mean I'm expecting it, or acting as if it's guaranteed or anything either.
-----------
In other words, Introverted Pessimist.
But it would be more accurate to say "Introvert with Extrovert desires, who is a Realist".
