I like balance. work vs play, liberal vs conservative, spending money vs saving, eating healthy vs eating delicious, killing spiders vs letting them go.
I also enjoy sci-fi and fantasy things. I've even attended a couple conventions, but I've never been so into it that I dressed up. Once again there is that whole balance thing. So if you enjoy the odd nerd-out, I think we could get along.
I usually end up INFJ or INFP when I take those Myers-Briggs tests, and it sounds pretty spot on.
