I think you are right on about the approval seeking. I still have vestiges of that (maybe EVERYONE does, whether JW or not), although as time goes by, I feel it less and less.
The only thing I think I did for MYSELF, not for anyone else, or to show how "theocratic" I was to others, was to read quite a bit from old watcher/awake periodicals. We had quite a set at home when I was a teenager; I know I spent a lot of time perusing the various articles. Just for my own knowledge. (I hated service/generally disliked meetings).
Funny. I think that very activity REALLY helped me come to terms with the inconsistency, the periodic changes in doctrine and the various changes due to social pressures the WBTS had to contend with. For example, check out their comments about women being raped. Just a few years back, the JW literature basically implicated MOTHERS treating sons badly as the reason for their anger, and subsequent rape of women! Also, women were guilty of wearing seductive clothing, which obviously enticed poor men into raping them. Good grief!!!!!! Obviously, the society's position on this issue has HAD to change over the years, but is very revealing. I think by reading thru their literature, with an open and inquisitive mind, I came to the obvious conclusion that it's NOT the "TRUTH." Not even close.
