there is an abundance of information about these personality types on the internet, I recently was participating in a forum dedicated to the whole Jung typology method.
It is a useful tool in learning how we react to certain things, I personally have not been able to get very far with it because my over active Thinking function blocks me from being able to tell where my other preferences lie. Still I see no harm coming from sharing this type of thing with others.
I'm glad to find people interested in it. I have several e-books related to the subject i believe, but there are ethical implications involved in sharing them. not that that bothers me but I've been slacking on reading the forum rules... lol i'm such a rebel right?
