I agree with that one. They have to be both sexy and smart. As for the sexy part, you can figure that out by putting your made-up date under the shower. If she still looks decent with all the makeup down, date her and glean a chance to see her mum, to get an idea what she'll look like in 20-30 years. If her mum's still so sexy that you'd bang her as well, chances are you're onto something! As for the "smart" part, that's pretty easy to figure out, but even harder to find... Hey, regarding personality types; I think I'm an ENTP, and I think my girlfriend is an INFJ. That's really quite funny, since we're opposite in everything, except the N... Going pretty well though. Perfect fit!
LOL... Try posting a personal newpaper ad explaining you're a INTJ looking for a steady relationship... LOL
Reflecting back from all the relationships I had, I had to admit opposites were the more fun ones. In the end of the day, only things matter is if you love her, if she loves you, and if she has a good heart.
