It's funny how Ti makes one less bothered, to the point of not caring and not trying. I find it hard to balance it, because it figures out that it would be best to play computer games and not bother with thinking about girls... This is probably why an ESTP would suppress it, because their Se knows instinctively that sex is the best thing in life.
Because I've been exposed to so much Ni now, I've gone and set my Ti on what Ni told me and it has now come up with "the answer to life, the universe and everything" - for real! It's quite simple and probably the problem people have in trying to figure it out is that they can't accept it, rather than that it's really a mystery.
The answer is that everything we identify with - thoughts, feelings, sensations, intuitions, ego, ambitions, drives, you name it - are all EFFECTS of material. So it can be logically said that material itself is MORE "divine" than anything else we identify with. This is very hard for most people to accept, but I have come to accept it now.
Where it would be used in getting a girlfriend, I don't know. Any dumb animal can get a mate - so I have always assumed there must be something really simple and easy about it that doesn't require thinking about, which is why I never even bothered about it until recently. It turns out I may have also been duped by all this stuff about "how to get a girl" and having to understand it all (at least I didn't pay for any of this stuff). It'll probably happen to me if I just put myself out there and try to interact :)
