It would be a toss-up between ISFP and ISTP. ISFP is appealing because you guys tend to be so artistic and I would probably become some amazing graphic designer if I were an ISFP. ISTP would also be nice because it fascinates me that anyone could be a "self-contained unit". It would be amazing to be satisfied with just my own company and not feel lonely. I only feel that way now when I'm painting or drawing. Also, I would like being an ISTP because then I would be able to figure out how to fix things (I am terrible at that!). Also, SPs in general tend to be pretty upbeat, I think, which would be a nice change from being someone who is so horribly serious and worried about the world's problems!
