I don't really have anything new to add to this thread it seems, but anywho...
I'd like to be...
ENFP-It would be nice if I didn't find social situations quite so tiring. Also helps that ENFP's are generally pretty well liked.
INTx (yes I would want to be right on the line between J and P)-F is my weakest trait, so I could definitely imagine being an INTP. I'd just prefer a strong helping of tertiary J if I went down that road so as not to risk appearing too schizoid.
ISFP-I have a feeling I'd be better at the many non-characteristically N things I like to do, i.e. guitar, cooking, soccer, running, lifting, etc.
Would not want to be...
an SJ. Don't get me wrong, my best friend is an ISTJ (he's an EMT and a hardass), and were I a guardian that's what I would choose, but it's just not for me. I think being an SFJ would be especially difficult, but we're just talking about me here.
Were I a thinker I'd be happy with any intuitive type, but being an STP also seems like it would have its perks.
