Well, being ancient, as I am, I'm actually on my fourth function, Te.
I think I always had a very strong Ne and Fi. I can't remember not having a healthy dose of both. Maybe that's due to my INFP father, who encouraged both of those things.
I've now a pretty good S, but, of course it's not as strong as a dominant S person, but it's good enough to serve me rather well, and I still find myself attracted to developing it more.
It's weird, but I've followed the MBTI type development theory to a t. And only because I've gotten attracted to that function at the time. And by that I mean, I've developed both Fs and Ns first, then toward midlife began on the S's, and now Te is the most difficult. I already developed a good Ti, from all the academia I've been through.
Te, is still a huge bother. Te for me, means not taking what people say and do personally. To use objective analysis on the outside world, or basically when dealing with people. I'm much better now, but far from where I'd like to be.
Here is my cognitive processes test, I took a while back. Maybe I'll take it again. As I said, I have a very strong Ti and Ni, which is out of the 8 sequence tract. But it makes total sense. I totally agree with this sequence of functions I have here, in terms of development. I really don't agree with the 8 sequence thing anyway, but that's another thread.
Ni - 31.2
Ti - 30.3
Fe - 29.2
Se - 27.2
Si - 15.6
Te - 11. 6
