zomg, I just realized that a book I read a while back that I thought had been written by Steven Covey had actually been written by Brian Tracy.
Anyways, based on what I remember of him, I think he's probably Se creative. LSI is my best guess.
He attributes his success to finding out what successful people do and doing the same thing until you get the same results. He suggests other people do the same.
He's clearly rational, and I think he's logical, and he doesn't seem like an obvious Ni type.
I was thinking LSI > LSE?
