Largely because of this thread, this morning I was thinking about the effect of positive thinking on one's ability to accurately assess a situation and form objective judgements about things. I used to think about this a lot, years ago, and sided with being objective over being positive. My job qt the time was essentially dependent/based on objectivity, though. Now, my work involves more people-focus, and I think the calculus is different. (sounds a lot like T vs F) Anyway, I spent the day forcing myself to think positively, something which I haven't done in a long while, and it really did make things a lot better. Fuck everything else, having a positive attitude just makes life more enjoyable. I think, ultimately, what you gotta realize is: when is it time/what are the things about which I must put on the serious face and be all objective-like, and when are the times/what are the things about which it's better to just put on a smile and be a positive force.
As for your description, Starry, that's how I've always felt about e7s (and e3s, in a similar, albeit somewhat different way): under the positivity on the surface lies what likely either is or has a very good chance of turning into a train wreck, due to unwillingness to realistically/objectively assess what is going on in their lives. "Oh, yeah, snorting this line and having sex with this stranger who I'm pretending is my super close friend but who I really don't know jackshit about is EXACTLY what will make my life PERFECT right now *brushes under the rug the fact that if he/she had to spend the next hour alone in a room they would probably drive themselves up the fucking walls trying to not think about everything that's going wrong in their life that they're actually CONSTANTLY trying to not think about/avoid, and thus never actually effectively dealing with/resolving* *snnnnnnnnnort* *awwww* *where were we?*"
/ apparently could only remain positive for one paragraph :P
