Okay, so I'm fairly new to MBTI. I've read Please Understand Me II, which seems to be pretty contraversial in these parts, and also the Tiegers' The Art Of Speed Reading People. I've also been snooping around a lot of internet resources and such. Point is, I have a fairly good grounding now in that i get the basics of preferences, cognitive functions and the like.
So the question is, what now? How do i get to the point at which i feel confident enough typing people that i can confidently act on it and adapt my behavour to their type?
As i see it there are 3 ways: Observing lots of people and putting the basic knowledge i have into lots of practice (which has the disadvantage that i could go way off), reading lots more theory (which has the disadvangage of being fairly inconsitent and controversial it seems) or reading lots of profiles of people, guessing their type and then seeing what other people have said.
How did you guys get into personality typing in a big way? I'm prepared to put in a lot of effort, but I don't want to waste time reading stuff that's not gonna help or practicing an incorrect skill to incorrect perfection. I read the thread on the seemingly pretty controversial way in which keirsey divides the types up into quadrants. Where else is good to go to find out about other ways of splitting it up, for example.
In short, what sort of resources (or specifics even better) are good for getting very pro at personality typing very quickly, and what sort of things do i want to avoid.
