As has been pointed out there are two things that happen - one you get deeper into it from an organisational point of view, or two you realise how unchristian it all is with endless man made rules.
I was fortunate enough to be so worn out by it all that I wasnt feeding myself all the propagander from their literature, only hearing some at the meetings. Even that was enough to draw me right in though. But I never got appointed because the closer I became and the older I got the more my eyes were opened to the politics of the congregation, something I didnt want to be a part of. I remember being one of a group of friends who were all servants except me, and they would talk about which job's they wanted and boast about it all to each other. It was like a popularity contest.
